f f Main Injector / Recycler Phil Adamson March 14 th 2014

f MI Downtime f

f Nu. MI f • Reasonable week • Close to what we consider nominal intensity (25 E 12 protons per pulse)

f • Intensity and Sea. Quest duty cycle seem to be rather strongly correlated • Real or artefact? SY 120 Injection f

f Resonant BPM intensity • Progress being made on spill intensity monitor (yellow trace) • Need a couple of calibrated intensity monitors before increasing intensity f

f MI/RR Loss Monitors f • Much progress towards continuously live loss monitor system • Necessary for efficient use of recycler • Next live test next Mon / Tues • Some fine tuning (eg. Pedestals) can happen after we go live

f • Vary quad in 8 Ge. V line • Observe oscillation in vertical beam width RR vertical IPM f

f • Plot since Monday • BSSB upgrade Tues am to allow $15 to Nu. MI • Scrub with 2 pulses per minute since • Whole ring shows same trend • Keep on over weekend… Recycler Vacuum f

f Job List Next Week • RR 232 Lam flange/beam box • Ready next Tues? • Do 901 BV at same time • Alignment at RR 102 (investigate half-inch offset question) • Alignment at RR aperture hit list • Dress cables in tunnel • Test RR heater tape at 52 region • Replace ISO-amp for 20 house VCBs (U most important) • Install 360 Hz traps in quad and bend supplies • Parts available? Later f • Replace 52 Ming-Jen multiwire paddle • MI V 103 IPM installation • MI 620 electron beam scanner installation • MI 201/202 remove e-cloud lossy cavity • RR 102 MW wireplane swap • Needs jig to handle 100 lb guts
