8 pack meeting notes – October 9th 2001

 

Agenda:

1.      Davis-Bacon determination

2.      Klystron progress report and plans

3.      Budget and Schedule.

Notes:

 

  1. Davis Bacon Determination
    1. D. Schultz compiled a list of work that detailed which work should be Davis-Bacon and which work is not.  He is submitting this list to the Davis-bacon committee which will review it and then it will be sent to the Oakland DOE office. 
    2. K. Jobe pointed out that RF cable should be in house because all of the previous NLCTA cables were contract installed and they all had to be reterminated.
  2. Klystron Update – J. Cournelle
    1. Update presentation (.ppt)
    2. First XP-3 started exhaust on 10/5/01.
    3. There are three XP-3 tubes being built now.  The first is a SLAC tube, the second is a CPI tube and the third is another SLAC tube.  The first two tubes have all of the parts needed to finish them.  The third needs a few more parts.  A fourth tube needs many parts to be finished. 
    4. Question:  Should a Toshiba X-band tube be purchased, so tubes made by all manufactures can be tested? 
    5. Question:  Can design specification be put on the web?  Yes.
    6. Question:  What is the efficiency?  60% is the design
    7. Question: What happens if the efficiency is low?  Will need more power form the modulator.
    8. Question:   What are the radiation shielding requirements for the XP-3?  The lead used for shielding should be designed into the klystron assembly and this assembly should have an earthquake specification.  Will be address offline.   The first two or three klystrons tested in the Klystron Lab will have many diagnostics and will be tested in a lead house, so they will need to have lead shielding added
  3. TWTA – J. Cournelle
    1. What are the output specifications for the TWTA.  S. Gold should have them and J. Frisch shold be the one to check them.
    2. TWTAs should have a rack near the klystrons.  There will be two racks near the klystrons.
  4. Water System – J. Sevilla
    1. Water pressure requirements are 120 PSI.  The current available pressure in ESB is 80 PSI.  Will need to buy a booster pump to reach 120 PSI.
    2. Chiller will also be purchased to cool the PM (permanent magnets) which focus the klystron beam.
    3.  Question:  Does the modulator cooling need to be de-aired?  To be determined offline.

 

Action Items:
