Minutes of RESULTS, PITZ Physics Seminar, 21.12.2011

Project: PITZ
Participants: Mikhail Krasilnikov, Georgios Kourkafas, , Dmitriy Malyutin, Igor Isaev, Ji Li, Marek Otevrel, Grigoriy Vashchenko, Keerati Kusoljariyakul, Martin Khojoyan, Dieter Richter, Roman Martin 

Agenda:
1)	D. Malyutin: Longitudinal Bunch Profile Measurements with TDS
2)	Ji Li: Emittance growth due to multiple transverse magnetic modes in an RF guns (paper from Pohang group)
3)	Announcements

Results:
1)	D. Malyutin: Measured longitudinal profiles are ~identical to simulated ones
2)	D. Malyutin: for 1 nC: longitudinal resolution 12um (40fs), for 0.1 nC: longitudinal resolution 6um (20fs) can be achieved
3)	Ji Li:

Next steps:
What is to be done?	By whom?	Until when?	Done on	
Include optical readout to estimate resolution	D. Malyutin	January 2012		
Clarify what means “0 degree TDS phase”	D. Malyutin	January 2012		
Check why the Gaussian pulse on average gets less energy than the flat-top part	D. Malyutin	January 2012		
Use slice vertical size to check resolution estimation	D. Malyutin	January 2012		
Check Gaussian+flat-top with larger laser spot size on cathode	D. Malyutin	January 2012		
Magnet optimization for longitudinal phase space measurements still to be done	D. Malyutin	January 2012
