COMMENT ON PSS Injector Segment PLC Upgrade

Log Number: 3876851Logbook(s): Body: 

During attempted certification of the PSS Laser Interface it was discovered there is still a problem with the Inline Dump position feedback to FSD, preventing operation of the Laser controls.
After a little bit of troubleshooting, due to complex wiring, we've decided to postpone further investigation to day shift. Correction of this issue should not require access to the tunnel or Injector segment lock up.
Before this snag, we were able to complete Static tests of the PSS Laser Interface.

COMMENT ON Injector Upgrade - Phase 1 Installation (Gun to Chopper)

Log Number: 3876850Logbook(s): Body: 

Day #158, Week 32 Day 3, Wrap-Up:

AIPINJ --
* PSS Certifications progressed, but not completed due to snag with inline dump FSD. SSG to T/S tomorrow.
* IN02B11-powered trim magnets inductance measurements completed. 3876843
* IN02B10-powered trim magnets resistor installations continue. 3876843
* UHV ion pumps voltage setpoints adjusted, largely eliminating previously seen noise. VIP1I01 may need hi-potting. 387682{2,5}
* Wien HV cables connected to all four electrodes. Pics -- 3876829
* Laser steering mirrors checked and found functioning as expected.

iocch3 in CED

Log Number: 3876849Logbook(s): Entry Makers: moserBody: 

Per Robert Norton: iocch3 is not decommissioned.

Figure 1: CED reports otherwise. Figure 2: Once placed back in production, HCO System will need to be set to IOCs, then Component Participation updated accordingly. With Cryo input, I can assist with this.

COMMENT ON Test Dominion Automatic Voltage Regulators

Log Number: 3876847Logbook(s): Body: 

Everone (JLab and Dominion) was on-site and in-place today, but the Main office in Richmond was dealing with a more important problem and could not break away for our test today. Will reschedule for next week with an eye toward a follow-on day in case there is another problem.

COMMENT ON DC Power Support for Injector Upgrade

Log Number: 3876843Logbook(s): Body: 

The inductance measurements has been done on all the
magnets in trim rack IN02B11, the trim rack was place in Low
Power Mode which is half of the normally operational voltage
of the trim rack.

It will stay in Low Power Mode until the PSS group are ready to
use channel 26 in the trim rack, I will then ramp the trim rack
voltage up to it's require setpoint.

The resistors installation on the Injector girders are continuing
and the IN02B10 trim rack magnets verification will continue as
well.

Follow-up Re: iocch{3,5,7} Comm Status

Log Number: 3876826Logbook(s): Body: 

Iocch7 has (for some time) been decommissioned and replaced with iocsoftch7.

iocch3 and iocch5 seem to be functioning just fine, with cryo's guard alarms and checks on these showing they are fine.. If there is an updated version of iocAdminLib that is desirable for doublechecking this remotely, can that version be provided?

I don't think this will be any kind of delay or problem since the underlying hardware is performing just fine as far as I can see.
