COMMENT ON Magnet warm region girder work - SAD 2023

Log Number: 4159512Logbook(s): Body: 

Magnet Measurement:

We completed torque checks on QJ quad on girder just down beam of 1/4/ Cryomodule. We also wired the QJ-6, hooked up LCW and turned LCW ON. Leak check is completed and in good order.

Matt-the Hamison correctors are ready to mount, if you need assistance just shout.

COMMENT ON PSS system upgrade SAD 2023

Log Number: 4159510Logbook(s): Body: 

Corrected field wiring of MBO dipole monitoring system (analog signals).
Corrected wiring of the East Arc Beam Stopper (disconnection of old, unused pressure switch cables).
Corrected safety relay feedback signal wiring of SL RF14 interface chassis.
Completed assembly of position switches on Aperture A4.

Laser stage measurement

Log Number: 4159509Logbook(s): Entry Makers: brukerBody: 

Looked at beam spot on "virtual cathode" camera as a function of laser-stage position. 5 points per axis, not great but a useful first data set. Tad bit tedious because the camera software is about as crappy as that for the UITF camera, if not worse. Per usual, the only function the user needs is not there.

Figure 1: Center and width of Gaussian fits in x and y applied to beam profiles integrated over the other axis, respectively.
Figure 2: Resulting stage calibration.
Disregarding the sign inversion of y (sloppy analysis), we get about 0.97 mm per 1000 stage units in x and 0.91 in y.

COMMENT ON Spring SAD 2023 RF Work Tracking

Log Number: 4159507Logbook(s): Body: 

Tried re-installing waveguide pieces in 1L26 but only two cavities, 4 and 8, were aligned close enough to complete installation. Other six cavities will require new pieces measured, cut and fitted. These cavities might be fitted with short waveguide adapter plates we have on hand but will most likely need to be broken apart and fitted depending on the offset we need to make it a closer fit. This will also require more of our ladder platforms, ratchets and multiple techs to hold up pieces.

injector work summary 6/1/23

Log Number: 4159506Logbook(s): Body: 

Greg activated the NEGs inside the dif pump station downstream of the booster. Combined ion pump current 15uA and falling.
Marcy 'conditioned' the three NEG pumps in the chopper region. She will perform a full activation tomorrow. Then we can remove the pump cart to provide better access to chopper for HCO
Larry and Sam made good progress with waveguides to booster
S&A completed 2B alignment of the phase2 girders, nice.
Phil provided assistance to SSG, the SSG boxes are now bolted to floor near beamline/A3/A4 and MBO dipole

COMMENT ON Modify 0L02 RF drive system for booster upgrade

Log Number: 4159492Logbook(s): Body: 

Waveguide installation for the Booster has started with the 400W waveguide (cavity 7) being test fitted. All gaskets will be installed and flanges properly torqued tomorrow. Klystron waveguide (cavity 8) will be also worked on tomorrow. Techs: L. Farrish and S. Holben

NEG activations: 0I02, 0I04 and 0I05

Log Number: 4159488Logbook(s): Body: 

NEGs were conditioned today prior to a full activation tomorrow.

Ion pumps VIP0I03, 4, 4A and 5 were disconnected from power supplies. VIP0I02 was powered and monitored locally during the beginning of the conditioning.

COMMENT ON Dogleg Power Supply PM's

Log Number: 4159485Logbook(s): Body: 

PM's complete for Doglegs 3, 5,7 and 9. Dog 1 will be complete this evening/first thing in the morning. We will still need to do checks under control power. We will complete at a later date.
