Diagnostic beam line
Dedicated High energy beam transfer line, with:– Energy measurement
• Time of flight (resolution 10-3)• Energy spread measurement (10keV to 20keV resolution)
– Beam Current measurement • ACCT : 5Hz-7MHz, 10µA rms on test bench, • Bergoz DCCT, • beam stop (electric and power measurement)

•EPICS linked to different subsystems (CAN, GPIB, Field Point) has been chosen as control system,
•Industrial PLC (SIEMENSTM):– Source and LBE Vacuum,– RFQ Vacuum,– LHE Vacuum,– Safety rules,
•Already working (SILHI/LBE, low level RF,…)
•New realization in progress (RFQ/LHE Vacuum, safety)

TRASCO RFQ tests
Test done on a separate cavity to allow conditionning of 2 couplers
• Windows conditionning OK until 150kW peak at 75% of duty cycle
• Windows conditionning OK until 120kW CW
RFQ tests
• Conditionning OK until 220kW CW• X measurements at 80kV never
exceed the noise level of the detectors
• To realize those tests, we used our analogical LLRF, this enable us to see the LLRF improvements to do

Conclusion
The installation IPHI (will) provide:
IPHI beam (CW or pulsed)3 MeV - 100 mA: 300 kW
RF power of the platform IPHI352 MHz up to 2 MW CW, need to be improved for pulsed operation and better reliability
A facility for high intensity accelerators and for ADS
