Tab Galardo , Millstone 781-981-5725 or 5749

Ask about RG220 for hv cable. He'll check warehouse

Haystack no. is 978 692 4764

from Tab: "for the BMEWS klystrons, the line manager is now Anne Winters (Walters?)(was Winston Parish). John Halberg is her asst. at McClellan AFB. Clear Alaska's BMEWS site will be upgraded to a phased array. Feb. 2001 is set for the commencement of the upgrade. When will klystrons become available? The Air Force knows that the only users of the tubes are Millstone and Arecibo. Clear has two spare L-3403 klystrons that are the chief engineer's "pets". They may have 7 more. They have 18 transmitters each running 2 each 5773 (high efficiency version of the L-3403). The tube we recently sent to Millstone is working fine. They are back on the air but have zero spare tubes. I told Tab we may have from 4 to 6 spares left. He has another magnet that he could send (and probably would trade right away for another tube).

mar 18 - Called Tab 3:30 not there - took the day off

mar 19 call tab at 14:33 AST: large cable was 300kV 100A. He has other huge spools down in the warehouse. I gave him the dimensions of RG-220 and asked that he look for a spool with more than 1300ft. He'll go back to warehouse , check and call back.

Klystron failed last night in cw operation after 9 minutes. Supposedly good spare showed max vac-ion current as soon as filament was turned on. Victor says it's shot. Leaves us with only one tube. We can reconfigure tx for single-tube operation.

Called Litton, Don Rosenbaum (drosenbaum.littonedd.com, 650-591-8411 ext 2285, Fax 650- 508-1956) . Tab Gallardo has very recently asked Litton about procuring a tube - seems as if Litton might have one stray tube on hand. Tab has dealt in the past with Litton's Dick Bartlett. Bartlett has turned him over to Rosenbaum. Rosenbaum had in front of him an email sent to Tab by Bartlett on 3-24-99 with the following prices:

test and evaluation: $15,000

minor repair (eg fix a leak): $25,000

major repair (eg new gun): $130,000

total rebuild (the most common option): $180,000

new tube: $210,000 (Supposedly a 5773, since they haven't built a new 4303 for years).

Rosenbaum will email an up-to-date quote (latest prices) to me and to Tab before the end of this week based on a quantity of 4. He would like us to fax him a list with the serial numbers of the tubes we propose to have rebuilt.

Litton has promised the government to keep this repair line going one more year as that should be enough to keep the Air Force on the air from Clear until the phased array is ready. The Air Force has been having 5773s repaired, a couple at a time, to avoid critical shortages. Rosenbaum had the impression that the Air Force will essentially use up the 5773s by the time they go off the air.

9-21-99 Phone Tab Galardo

He has two good tubes in one transmitter. No other good tubes.He is trying to get the two "pet" 3403s from Clear, working through M.Sgt O'Hare(at McClellan?) , using the argument that Haystack is a "back up sensor" for the 84' Haystack radar. He's being helped by the leader of Linc. Lab Group 91.

Old Litton names mentioned again by Tab: Bud Helms, still consults some for Litton,

Stan Andrews 3403 expert, test engineer.

Tab got two klystrons from Fylingdale. He asked for directional couplers but was sent several boxes of hybrids (of which he already had many). Fylingdale had 22 tubes. Some may have been sent to Clear. Tabl says that much of Fylingdale was bought by scrap dealers in some deal that embarrasses the Air Force.

Haystack used Eimac 626's (ext cavity tubes) until around 82? when Wally Reed rebuilt the transmitters to use the 3403s. It seems that the AF furnished them tubes for free! for several years beginning around '83 - some 20 tubes in all and some of them brand new. This during the time that George Gerraut was supervising the tube supply from Space Command in Colo. Springs. (Tubes were always warehoused at McClellan AFB, Calif). Recently (92? 94? 98?) the AF was ready to ship 15 each 5773s to Tab. This time, however, they wanted to know what line to charge them to. Tab told them that they never were charged before. The tubes didn't get shipped.

Re: Turkey had a top secret radar that used 626s for years. A couple of 3403s were shipped to them. Tab was later offered these tubes. He had someone open the coffins and found the guns were broken off both tubes.

Haystack has, over the years, extensive used military and governmental contacts to obtain tubes and other parts.

10-7-99

Conference call re. klystrons: Rich Behnke, Bob Robinson, John Kelly, Mike sulzer, Don Farley, John Foster, Don Campbell, Tab Gallardo, S. Basu.

New info: Phased array at Clear is complete. In an initial test it failed to detect a missle. The old radar did dectect the missle so Brig. Gen. Mike Drehnan gave orders to keep the old radar running in parallel with the phased array for one year, while the bugs are worked out of of thearray. (Clear Air Station at Eielson AFT, AK is home to the 13th Space Warning Squadron. The squadron is assigned to the 21st Space Wind, Pete AFB, Colo. whose 12th Squadron runs Thule). John Foster pointed out that if Clear is shut down the way Fylingdales was, the tubes might be jerked out of the sockets and put outside (to freeze) before we even know about it.

NSF should arrange with the AF that the tubes be removed, protected, packed, and shipped before the rest of the old radars are dismantled. Protection could (should) include filling them with alcohol or other antifreeze.

SLAC makes! its own klystrons. John Kelly approached them and was told that they would consider rebuilding BMEWS klystrons. Sounds like a good bet. Littons offer to supply tubes seems too expensive and too late - they would deliver at the same time the Clear tubes should be available. So SLAC might give us some slack while we wait for Clear to close.

The phone conference seemed to end with the idea that Clear might close w/o notice and the tubes could be carelessly hustled out into the cold to freeze by the contractor hired to tear down the old radar. NSF should arrange with the Air Force to have the tubes removed, protected and packed before any other dismantling begins.

We have meter relays in need of replacement or repair.

I'm looking at "api Part No. 47-1820-2001 Model no. 461C".

This meter (manufactured by api?) is what we need, except

we need to trip on low rather than trip on high. Meter is

4.25" high by 4" wide. Movement is 50mV fs. Calibration is

"0 - 10 D.C. AMPERES". Can you help?

Sincerely, Jon Hagen

Subject: Klystron rebuilder

Monty Grimes (MIT) gave Edgar Castro a lead on a possible klystron rebuilder: California Tube Lab. I phoned CTL today (831-761-1199) and spoke with Jim Martin. My impression is that they probably can repair klystrons that only need a new electron gun. The company has 35 employees and has been in business for 50 years, mostly rebuilding broadcast tubes and occasionally building new tubes.

Here is what they offer: For $350, they will cut the weld at the bottom of the tube and pull out the filament/cathode assembly. They then examine the drift tube with a bore scope optical device. They are not equipped to repair tubes with damaged drift tubes or damaged cavities. (Drift tubes can be melted if the focusing magnets fail and allow the beam to go off center. Cavity tuners can have mechanical damage). They pay another Watsonville company,

Spectramat, to make a new copy of the filament/cathode. (This company may have made the original). The new assembly is welded in, along with a new vac-ion pump and a new pinch-off vacuum connection. They pump and bake the tube at 500 deg. C for about 3 days. Their baking oven is 12 ft high and 4 ft in diameter, easily large enough for an L3403. They are not equipped to do high voltage or RF testing. (Litton proposed the same arrangement, as they dismantled their test stand some time ago). They ship the tube back with specific burn-in instructions. If the tube is satisfactory , the customer pays the repair charge $60k to $70k. The tube then carries a warranty that is the "same as the manufacturer's warranty."

Have they ever rebuilt a Litton L3403? No. They've done lots of UHF tv klystrons. Recently they rebuilt some other large klystron(s) from Vandenberg AFB. California Tube Lab is in Watsonvil,le, Calif. on the Monterey Bay, 70 mi. south of SF. They have a web site with photos and company information: caltubelab.com

Jim Martin requested more information on the tube. Yesterday I faxed him spec sheets, outline drawings, etc. CTL's fax number is 831-761-8211.

Subject: Half-height WR2100: shortening corrugated sections

These pieces (from BMEWS Thule) were most likely made by Mega Industries ( 207 854 1700). Ray Bachman of Mega says it will be relatively easy to relocate a flange to get the desired length. They can use silver braze on the aluminum flange. He asked that we send a section for evaluation and gave us a return authorization number:

RA 87036.

Subject: Mega can't fix the corrugated waveguide

Ray Bachman of Mega called this morning to say they received our corrugated waveguide section. They were surprised to find it had not been made by them. Their guides are made of aluminum and have parallel corrugations. Our guide is brass and has spiral wound corrugations.

They cannot fix our guide but they say it was made by Litton Airtron in Morris Plains, New Jersey. They suggest we contact Bob Hathaway at 973 539 5500 ext 352, FAX 973 539 5548.

I'll call him.

Wants verification of part no. 39973 and lengths. Call him and give him

this info (which I'd sent to Ray Bachman at Mega)

We have shipped you a long section of WR2100 half-height

flex guide for evaluation.

The crate is marked with the return authorization number you

furnished us, RA 87036.

We would like you to quote us a price on relocating flanges

on this section (and more of the same which we will ship

you) to provide us with the following pieces:

WR2100 Half-Height Flex Sections:

Item 1: 4 ea. length 16" (flange face to flange face)

Item 2: 2 ea. length 24"

Carl Hricko said he'd dig out the original drawing and call me back on Wednesday,

June 14 (Flag Day).

Aug 2, call airtron. Karl Kricko no longer works there. Talked to Bob Hathaway.

bhathaway@littonairtron.com

Will email him the info sent prev. to Karl. Gave Bob the RMA number to find the piece. They'd been on shutdown the last two weeks of July.

Aug 4, call from Airtron: Helgard Kirsch and John Swanson.

Wanted to know: paint? flatness? pressure? environment?

They'll call Monday to let me know if their mgtmt gives them the ok to do an evaluation piece (one of our pieces). They'll let us know the eval. chg. The final price will depend on how easily they can do the work.

Monday, Aug 7, the call from Airtron: Joe Machalsky (shop guy I think) needs virgin flange fi we have one. Success guaranteed with virgin flange. Not guaranteed for reworking old flanges. Turns out the flanges must be plated with a series of metals to end up with a solderable surface and to prevent galvanac action that would cause the flange to rot off the waveguide. They'll fax us a quote: $2000 for a best effort first attempt.

Friday 9-1-00, call airtron , Helgard Kirsch 973 539 5500 - says they've cleaned and plated the flange. Think's it will be perfect. Said he'd call back in 5 min with status......

Call Paul Lane at Signatron re acceptance tests of VLBA-4 terminal.

All ok for Tuesday, June 27. He'll be talking to Dan Smythe of Haystack today.

Email'd Andy Dowd re. Tuesday morning at Signatron. Have to call Haystack.

To get to Signatron - take 62, cross Assabet river, go quarter mile beond Damon Mills.

Tuesday - andy email'd back. Said he hasn't made a concerted effort to be free next week "given Signatron's track record" but that he can be there on Tuesday until 11:30 and again on Wed. He thinks the zero-baseline test is crucial. But the Signatron test plan doesn't include it nor did Dan Smythe think it would be included.

Phoned Paul Lane at Signatron around July 25. Paul said they had indeed found that the write card was faulty (previously untested pc card design?). Paul gave the impression that they'd be ready to pass factory tests within maybe one week.

Aug 9 - heard nothing from Signatron. Phoned Paul Lane. He expects to be ready by aug 21, the date on which Dan Smythe will have been back a week from his vacation, prepared to do testing. Paul expects to demonstrate the originally scheduled acceptance tests in the presence of Dan and Andy and also to do a Zero Baseline test - with Dan checking the tape at Haystack. At this point we would surely sign off on the factory tests and accept the unit, prior to sending to Haystack where the operation of the formatter and decoder (and the rest) would be very carefully checked by the designers of these modules.
