Injector: Transmission optimization
Log Number: 4187929Logbook(s): Entry Makers: hoflerywangBody:
Fig. 7 shows the minor steering changes upstream of the Booster (left column) made to optimize transmission for A (45 uA CW) and C (45 uA CW) beams relative to the previous Injector reference save (allsave 24382, right column).
With beam to the ILD, Figs. 1-2 show 45 uA CW for A (zero-pos with A beam), and Figs. 3-4 show 45 uA CW for C (and C's orbit relative to A's orbit).
In anticipation of delivery for Hall B, we checked the B orbit to the ILD with Tune beam, and the B orbit looks good (Figs. 5-6).

Laser work today
Log Number: 4187905Logbook(s): Body:
KLong laser (15.6MHz) is aligned to the photcathode today during the MD time. The beam size is comparable to other lasers, 1mm (FWHM), a bit less than B, larger than A and C. In priciple it can be used for beam study now. Some improvement on the control is needed but won't affect laser operation. The laser was left off and can be tuned on when it's needed.

Injector: A3 interception
Log Number: 4187902Logbook(s): Entry Makers: hoflerBody:
With the as found orbit (same machine settings as reference allsave 24382), monitored 30 uA CW from C laser to FC2 to see if the spikes in A3 noted in the linked elogs occur independent of beam delivery to a Hall (and without a corresponding current lock) (Fig. 1). After ~35 minutes, A3 had a 1.3 uA step change in intercepted current, and prior to the step change, the intercepted current slowly increased by ~0.3 uA.
