TESTING OF NEW HADRON BEAM PHASE AND POSITION MONITOR AT CIEMAT LABORATORY

Libera Single Pass H is the new instrumentation intended for phase, position and charge monitoring in hadron and heavy ion LINACs and transfer lines. Initial measurements and verification of the instrumentation performance were conducted in the laboratory at Instrumentation Technologies. Characterization measurements of the real BPM prototype were later carried out at CIEMAT wire test bench [2] in Madrid. The measurements were performed with the 175 MHz bunched beam-like signal connected to the wire. Different measurements were performed on the test bench; first by moving the wire over larger displacements and checking the position sensitivity and resolution and later by changing the signal phase and performing the phase shift measurement. This article discusses the new electronics, the tests carried out in the test bench and the performance obtained.
