RunPlan

BeamTune

Tune beam into zero line, max current, 10.5 MeV energy, 20 ns width, 300 Hz rep rate

For Reference, below is the the tune used on last day of July 2012 Positron run

Measure Emittance

Ilyusha Background measurements

Previous Background tests during 2n correlation run

https://wiki.iac.isu.edu/index.php/2n_BKG_data

HV=1000 CFD = -12 mV


Previous run during neutron correlation experiment found 1 gamma/15 electron beam pulses

Tune beam into zero line, max current, 10.5 MeV energy, 20 ns width, 300 Hz rep rate

1.) Take a run with no shielding around Ilyusha

2.) Move Pb bricks around the scintillator to determine direction of background

3.) add shielding to accelerator


Rate (gama/pulse) Beam COnfig (E,pulse width,peak current) Configuration
10.5 MeV : 100 ns FWHM, 150 mV UNshielded illyusha scintilltor, 12 mV threshold on CFD, 255 CFD output pulse width


Electron/photon ratio

Compare magnet in and out using a scintillator at the exit window of the 90 degree line.
