WORK EXPERIENCE

ENGINEER-PHYSISIST

Stanford Linear Accelerator Center (SLAC), January 2005 – February 2010

Created software for complex magnetic measurements procedures for SLAC LCLS project. Was using National instruments LabWindows CVI and Real Time Labview to program FPGA modules.

As a result, the following measurements techniques were developed and setups were built.

The old Dover (made) granite bench that was running stages in open loop mode was upgraded with encoders and real time NI FPGA was programmed to generate scan triggers and to track encoder dust contamination as well as errors due to micro quakes. This was achieved by comparing encoder data against the multiple encoder indices located along the bench at every 10cm.
The new Kugler (made) bench came with the Y – motion range much wider than needed, and thus Kugler firmware had to be reprogrammed to allow for only 1.2 mm y-motion range The same FPGA system as for Dover bench was used at Kugler bench to generate scan triggers and track errors.
Unique approach was used to measure undulator field integrals with the long coil. The parasitic three – phase voltage induced by power lines across the coil was used as a sampling signal. A remarkable result was achieved by finding all maximums and minimums on the integral curve, and then by averaging each adjacent maximum and minimum. This approach surprisingly produces very stable results and does not change due to 60 Hz signal amplitude deviation.
The Hall probe calibration setup was build and programmed. Since the powerful electro –magnet produces a lot of heat radiation, the Hall probe resides inside the copper block with temperature stabilized by water circulating inside of it. A few calibrations of the same Hall probe show the difference well below the spec.
Since undulator properties depend heavily on temperature, the all time temperature measurement and logging was implemented. Dedicated server instantly measures temperature of all undulator as well as ambient temperature and broadcast them to all measurement setups. Thus every undulator measurement keeps track of temperature.
Undulator magnetic properties may significantly decay due to lab temperature change. This was a reason to build alarm system that was implemented to track lab temperature and automatically send telephone messages to designed users in a case of large temperature change.
Did undulator measurements and tuning occasionally when needed.
Integrated Matlab and IDL into C-based measurement programs.
