2 days 13 hours ago
Log Number: 4463330Logbook(s): Entry Makers: brukershukuiBody: 

Gun valve open, ITV2I01 inserted. A laser CW, attenuator 200.
Figure 1: as found at 13250 / 19250 (as used for last run)
Figure 2: spot to the right on the viewer at 12500 / 19250
Figure 3: spot to the left, scraping on edge of hole at 17500 / 19250
Figure 4: horizontally ~centered, moved down, scraping on bottom edge of hole, retro moves down, 15000 / 15500
Figure 5: moved up, retro moves up, 15000 / 20000

Shukui also found the retroreflection outside the laser window.
Everything behaves as expected.
Gun valve closed.

INJ Beam sync HCO

2 days 14 hours ago
Log Number: 4463320Logbook(s): Entry Makers: sethgBody: 

Seth Green and I took a look at the beam sync chassis in the injector. We measured the pulse width of all 3 chassis and confirmed the delay spec on the two that which had the delayed outputs being used. All three pass the routine checks for both pulse width, and the delay checks.

resultant images are attached in the zip file. Consider these components checked and ready for beam.

HCO of INX0L04 and INX0L05

2 days 17 hours ago
Log Number: 4463303Logbook(s): Body: 

performed HCO of INX0L04 and INX0L05. Switched the 1S integration time and 1000pF cap to a different value then switched them back to ensure the unit is configured properly in light of the recent outages. Let the chambers sit biased for a bit and found INX0L04's nCur to be out of tolerance. Probably fixable with autobias but flagging so its on our radar going forward. Will set INX0L04 to not ready and INX0L05 to checked.

CIS HCO: Photocathode

2 days 17 hours ago
Log Number: 4463302Logbook(s): Entry Makers: suleimanBody: 

Figure 1 shows the last QE from Sept 3rd, 2025.
Figure 2: shows the first QE scan from today.
Figure 3: shows the second QE scan from today.

The QE is larger than 0.3%, good enough for the initial restore of the injector. We will heat and activate in a few weeks.
