FrankGerigk 2007-05-08 ask for use of SF6 in circulators at GSI for new 3 MW klystrons a first test will be made without SF6 edit
Main.all 2007-05-08 redo ZTT plot for revised layout Linac4ZTT edit
FrankGerigk, RolfWegner 2007-05-08 prepare summary of pros/cons for PIMS/SCL for structure meeting SCL/PIMS comparison edit
MatteoPasini 2007-05-08 re-optimise CCDTL shunt impedance presentation edit
FrankGerigk 2007-06-07 PIMS: how much price difference does it make to have a 3-cell cold model or a 5/7 cell cold model? Does the slot shape make a big difference in cost? aim for Sept/Okt for results of the cold model. Discuss this with Gilles Favre/Rosario Principe. decided to build one 7-cell model (5% coupling) and one 3-cell model (3% coupling) with two different slot shapes (LEP type and modified, both for 3% coupling), approximate cost: 28400 CHF edit
MatteoPasini 2007-06-07 change in ZTT of CCDTL for stems with bigger or smaller diameter edit

FrankGerigk 2007-07-19 check if tunnels with small distances to the SPL tunnel are still in use TunnelDistances edit
MatteoPasini, RolfWegner 2007-07-27 write a report on the CCDTL prototype measurement and pick-up calibration CCDTL prototypes: test results, M. Pasini, M. Vretenar, R. Wegner, CARE-Report-2007-036-HIPPI edit
FrankGerigk 2007-08-09 ask Yannic for a pressure meter and compare water flow values with old estimates for SPL pressure meters are installed edit
MatteoPasini 2007-08-09 find frequency shift for CCDTL prototype, when going from air to vacuum and power for Linac4 and SPL duty cycle, compare tuned frequencies with Wanglers formulas CCDTL prototypes: test results, M. Pasini, M. Vretenar, R. Wegner, CARE-Report-2007-036-HIPPI edit
FrankGerigk 2007-11-02 find amplifier for 352 MHz CW test of PIMS and CCDTL there are 2 options: i) use the driver amplifier for the 352 MHz tube that was used for the CW tests of the French DTL model, ii) combine several of the 200 W LEP klystron drivers, P. Marchant from Soleil would be willing to help within a CERN/Soleil collaboration agreement edit
RolfWegner, MatteoPasini 2007-11-02 measure if there are different field levels in the two CCDTL tanks for different duty cycles Minutes09November2007 edit
