Minutes of RESULTS, PITZ Physics Seminar, 22.03.2012

Project: PITZ
Participants: F. Stephan, M. Krasilnikov, B.Petrosyan, G.Kourkafas, D.Malyutin, G.Vashchenko, Y.Ivanisenko, K.Kusolyariyakul, J. Li, M. Otevrel, R. Martin, B. Marchetti, A. Oppelt, M. Mahgoub, D. Kalantaryan, B.Schoeneich, L.Hakobyan, D.Melkumyan

Agenda:
1)	D. Kalantaryan, “Degaussing procedure ”
2)	R. Martin, “Transverse laser profile characterization procedure”
3)	M.Krasilnikov, “Emission studies udgrade from 22.03.2012”

Results:
1)	Updated GUI was presented and discussed, some improvements to be done.
2)	Definition of area of interest (AOI) obtained, analysis of AOI in terms of intensity
    done, polar Fourier transform started to define frequency spectrum of intensity 
    fluctuations.
3)	P_gun*sigma_x*sigma_y=const (invariant). P_gun – power in the gun, sigma_[xy] RMS sizes 	measured on the VC.

Next steps:
What is to be done?	By whom?	Until when?	Done on	
Topic 1				
define used groups of magnets on right side of GUI (e.g. LEDA, HEDA1, …), arrange them as convenient for shift	Info by Dmitriy,
Realization D.K.	a.s.a.p		
show current curves (SP + RB) for all degaussing magnets in main window
instead of ‘Open graph’ buttons	D.K.	a.s.a.p		
open preconfigured GUI for selected magnet group	D.K.	a.s.a.p		
Topic 2				
try Super-gaussian as alternative fit function for definition of AOI	R.M.	a.s.a.p.		
analysis of AOI should be done in terms of higher moments / covariance of the intensity difference distribution	R.M.	a.s.a.p		
Special spacial harmonics analysis (combination of Bessel functions)	R.M.	a.s.a.p		
Topic 3				
Jump of the power at the phase of max mean momentum. Klystron non-linearity	RF crew	a.s.a.p.
