Description
The Canadian Light Source recently replaced its aging linear accelerator (linac) with one procured from Research Instruments GmbH (RI). The original linac operated at a frequency of 2856 MHz, which is not a harmonic of the 500 MHz booster ring rf. The two rf systems were not synchronized and the linac beam was rebunched into the booster rf buckets, causing losses of at least 33% at injection. The RI linac is synchronized to the booster ring rf frequency through the 500 MHz pulsed gun and sub-harmonic pre-buncher. The RI linac S-band rf is also synchronized and operates at approximately 3.0 GHz, the sixth harmonic of the booster ring rf frequency.
In this report, we compare observations made while capturing the beams from these two linacs with different rf frequencies.
