THPOSRP07	An Optimized Delay Line with Temperature Compensation	65
	N. Shurkhno, A. Kononov GSI, Darmstadt, Germany R. Stassen FZJ, Jülich, Germany
	This paper describes the design and development of a low-loss, low-latency optical delay line that provides temperature stability within a given temperature range. Such delays are of particular interest for stochastic cooling systems, where they are used to synchronize a system’s correction pulse and in a feedforward loop of optical comb filters. However, commercially available optical delay lines have certain disadvantages for stochastic cooling - large intrinsic delay, high and non-constant optical attenuation, and overall delay drift due to temperature-dependent optical fibers. To mitigate these problems, an optimized optical delay line has been developed for the stochastic cooling systems of the COSY (FZ Jülich, Germany) and HESR (FAIR, Germany) accelerator facilities.

THPOSRP21	How to Adjust Stochastic Cooling Systems	98
	N. Shurkhno GSI, Darmstadt, Germany
	The paper summarizes techniques and algorithms for adjustment of stochastic cooling systems, that have been developed and tested at the COSY accelerator facility (FZ Jülich, Germany). An overall goal was to automate typical time-consuming manual adjustment routines. As a result, a set of algorithms based on a Fokker-Planck description of stochastic cooling process was developed, which allow an accurate and fast automatic adjustment of main system’s parameters. The methods have been elaborated and used at COSY during development and testing of stochastic cooling systems for HESR and are planned for further use at the FAIR accelerator complex (GSI, Germany). The methods are quite universal and can be applied or adapted to any similar system.
