Pseudo Single Bunch Project Pseudo Single Bunch Project
I. Introduction
Devising a way to increase the amount of effective single bunch time at the ALS is quite interesting for a number of users at the ALS. A possible way to create a pseudo single bunch operation is to physically separate the cam-shaft bunch from the rest of the bunch train. Kicking the cam-shaft bunch on a different closed orbit has some engineering challenges, however, it appears to be feasible. Whether or not the ALS users can effectively use this is another question. To test the concept, a 1.5 MHz kicker magnet has been designed and built. The installation, commissioning, and testing effort will take place in 2007. A workshop was held in June 2006 to determine user requirements and potential interest. The document links below provide more details on the kicker magnet and explain how a single kicker magnet can be used to test a pseudo single bunch operational mode.
