BSList #117047: pass 1 of parametric harp scans

2 days 17 hours ago
Log Number: 4466680Logbook(s): Entry Makers: brukerBody: 

After Tony found the problem with IHA0I02, I spent the rest of the shift testing how to make a comparative measurement of the phase space after the Wiens with VWien=0 and VWien=90 using the harp and MFX0I01.
As long as we are still working on the MFX0I01 calibration in parallel, the strategy for this part of the test is going to be to measure these two lens scans for different upstream focusing settings and empirically find the setting where the Wien has the least effect on the beam parameters, which implies minimum beam size inside the Wien.

IHA0I02 - control channel swap

2 days 19 hours ago
Log Number: 4466655Logbook(s): Body: 

Swapped the controls for IHA0I02 with IHA0L03.

OPS will have to use the controls for 0L03 to scan 0I02.

To view the harp scan, OPS will need to pull up 0L03 on the Harp Fitter Tool.

*IHA0I02 is inoperable
*IHA1D00 is inoperable

Harp debugging: 1D harp scan TM vs CS

2 days 20 hours ago
Log Number: 4466649Logbook(s): Entry Makers: brukerBody: 

Figure 1: 10 uA (during pulse) TM beam
Figure 2: 10 uA CW
Both on 1D harp. PGA = 128.
Pulsed beam is barely separated from the noise. CW signal is gigantic.
Unless it is supposed to be this way, we have an issue that affects both IHA0I02 and IHA1D00.
