Description
At KEK an electron test beam facility with beam momentum up to 5.5 GeV has been established since 2022. Usually the beam is available for sensor testing for three periods (May-June, Oct-Dec and Feb-Mar) in each year in total about 5.5 months. The beam rate at 3 GeV is more than 2 kHz with beam spot size of 2 cm (1 cm) in horizontal (vertical) direction in RMS.
We have a plan to improve the focusing the electron test beam line by modifying the beam transfer magnet configuration. We will discuss the plan and recent updates on the test beam line tracking system.
Also we have started to discuss a hadron test beam line at KEK Tokai campus (J-PARC). A test measurement has been performed to verify there is enough amount of charged pion for a hadron test beam line. We will discuss result of the measurement.
