1. MB-IOT test bench at CERN
Eric Montesinos

2. 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

Already available at CERN
To be bought by CERN

4. First draft test stand proposal
SPS 800 MHz spare TX
(to be validated at 704 MHz)
David did a more detailed study:
LHC2 is almost the only acceptable place
SR2 ?

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

Olivier agreed to lend one ‘LHC spare’

5. Second draft test stand proposal

Thales/CPI requested 10 individual units
Cost not included in the initial estimates
Thales will provide it and it will remain CERN property
Thales will make FAT at CERN’s test stand

David is taking care of it
LEP HVPS converted from CW to pulsed operation
Olivier proposed help of Gianfranco as well, I will use it for sure

7. 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

8. Already available at CERN
Two IOT
Main goal:
Double the tests capability
& to have the same test facility for both tubes, in order to better compare results

More or less the same difficulty as the first one
Higher safety issues ?
