MB-IOT test bench at CERN

13.01.15Eric Montesinos

K1577/AB Addendum 19• CERN & ESS will jointly study and agree a test programme

• CERN will source, prepare and make available test stands and equipment to enable test of relevant parameters and requirements

• The IOT will be tested for ESS and CERN SPL operational parameters

• CERN will allocate test time, resources and utilities for an extended test of the IOT > months

• ESS and CERN shall jointly prepare a report no later than October 2016 provided that IOT are delivered on time to permit the testing programme to be started no later than 01 October 2015

• The test stand shall remain property of CERN

• The IOT shall remain property of ESS

First draft test stand proposal

David did a more detailed study:LHC2 is almost the only acceptable placeSR2 ?

Olivier agreed to lend one ‘LHC spare’

SPS 800 MHz spare TX(to be validated at 704 MHz)

Two SPS 800 MHz spare loads (to be validated at 704 MHz, simulations ok)+Splitter to be designed and to be built

RF load

LVPSDavid is taking care of itLEP HVPS converted from CW to pulsed operationOlivier proposed help of Gianfranco as well, I will use it for sure

K1577/AB Addendum 19

• With Morten we now have regular follow-up meetings

– jointly study and prepare an agreement of a test programme

– Prepare agreement on equipment to enable test of relevant parameters and requirements

– I insist to keep ESS and CERN SPL operational parameters

• Just started, as right now IOT contract was confidential

Main goal:Double the tests capability& to have the same test facility for both tubes, in order to better compare results
