Degrader FC2 currents in 6x16 set up, 0 Wien

21 hours 9 minutes ago
Log Number: 4508719Logbook(s): Entry Makers: samariBody: 

readback was definitely noisy so pictured is the mean value along with the A5/A6/Target encoder positions. This was for the slightly bigger configuration. I was not able to get to the smaller beam configuration (4.5x11) step 3 of the BSList (taking the degraded data).

COMMENT ON Study of degraded beams correlation between emittance and current

21 hours 46 minutes ago
Log Number: 4508713Logbook(s): Body: 

Summary of 2026-06-04 beam study on day shift: C laser, 46.5 degree setup
Using as round of a beam as we could get at the degrader viewer ITG0L02A, degrader targets and apertures were inserted in all combinations possible with MPT0L02 solenoid current set to 95 A. Beam was previously centered on A5 and A6 prior to target insertion; we found that this beam was reasonably centered on FC2 as well. Varying the solenoid current about the 95 A setpoint did not meaningfully increase the current collected at FC2. Data in the archiver, to be analyzed offline.

COMMENT ON Nominal beam characterization for degrader comparison

Log Number: 4508712Logbook(s): Body: 

Summary of 2026-06-04 beam study on day shift: C laser, 46.5 degree setup
Performed a quad scan at IHA0L03 using MQJ0L02 for analysis of as found beam, then attempted to generate round beam at the degrader viewer ITG0L02A (https://logbooks.jlab.org/entry/4508531). We used this beam for emittance/current measurements BSList 120266. Analysis of quad scan to be done offline, as qsUtility was not available.
