MOPTY038 | NSLS-II Digital RF Controller Logic and Applications | 1010 |
|
||
The National Synchrotron Light Source II accelerator consists of the Storage Ring, the Booster Ring, and Linac along with their associated cavities. NSLS II is committed to the use of digital RF controllers for controlling these cavities. Given the number, types and variety of functions of these cavities, we sought to limit the logic development effort by reuse of parameterized code on one hardware platform. Currently we have fielded six controllers in the NSLS II system. There are two controllers each in both the Storage ring and Booster. The first controller in each is used to control the cavity field and the second controller used for diagnostics. In the Linac a controller is provided which modulates the eGUN grid to generate the bunches. Lastly, in the Master Oscillator Distribution System a controller is used to make phase corrections to the outgoing master oscillator clock signal to account for thermal phase drifts along the distribution path. | ||

TUPMA050 | NSLS-II Injector Commissioning and Initial Operation | 1944 |
|
||
The injector for the National Synchrotron Light Source II storage ring consists of a 3 GeV booster synchrotron and a 200 MeV S-band linac. The linac was designed to produce either a single bunch with a charge of 0.5 nC of electrons or a train of bunches up to 300 ns long containing a total charge of 15 nC. The booster was designed to accelerate up to 15 nC each cycle. Linac commissioning was completed in April 2012. Booster commissioning was started in November 2013 and completed in March 2014. All of the significant design goals were satisfied including beam emittance, energy spread, and transport efficiency. While the maximum booster charge accelerated was only 10 nC this has proven to be more than sufficient for storage ring commissioning. The injector has operated reliably during storage ring operation since then. Results will be presented showing measurements of injector operating parameters achieved during commissioning and initial operation. Operating experience and reliability during the first year of NSLS-II operation will be discussed. | ||

Funding: Work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-SC0012704. The National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory (BNL) is a third generation 3GeV, 500mA synchrotron light source. We discuss the booster synchrotron RF system responsible for providing power to accelerate an electron beam from 200MeV to 3GeV. The RF system design and construction are complete and is currently in the operational phase of the NSLS-II project. Preliminary operational data is also discussed. |
