Load test of RPC prototypes — •Christian Simon and Norbert Herrmann — Physikalisches Institut and Department of Physics and Astronomy, Ruprecht-Karls-Universität Heidelberg, D-69120 Heidelberg, Germany
The Time-of-Flight (ToF) wall of the Compressed Baryonic Matter experiment (CBM), conceptualized on the basis of high-resolution timing Multi-gap Resistive Plate Chambers (MRPC), is intended to account for concise hadron identification at an unprecedented event rate of 10 MHz. To explore the performance and limitations of the current design, high-rate tests with GSI/SIS-18 heavy ion beams irradiating the full surface of a 30× 30 cm2, fully differential multi-strip MRPC demonstrator have been performed in the fall of 2012.
A calibration scheme adjusted to the layout of the prototype has been developed and will be described. Preliminary results concerning efficiency and timing resolution will be presented as function of the incident particle flux.
