MB-IOT test bench at CERN 13.01.15 Eric 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 Drivers IOT HVPS Capacitor bank Crowbar RF load LVPS Already available at CERN To be bought by CERN

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 ? Drivers IOT HVPS Capacitor bank Crowbar RF load Two SPS 800 MHz spare loads (to be validated at 704 MHz, simulations ok) + Splitter to be designed and to be built LVPS Olivier agreed to lend one ‘LHC spare’

Second draft test stand proposal Drivers IOT HVPS Capacitor bank Crowbar RF load LVPS 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

Second draft test stand proposal Drivers IOT HVPS Capacitor bank Crowbar RF load LVPS 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

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

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 Drivers LVPS IOT HVPS Capacitor bank Crowbar RF load Capacitor bank IOT RF load To be bought by CERN Already available at CERN Drivers LVPS

Two IOT Drivers LVPS Schedule Cost IOT HVPS Capacitor bank Crowbar RF load Capacitor bank IOT RF load More or less the same difficulty as the first one Higher safety issues ? Drivers LVPS

Two IOT Drivers LVPS Schedule Cost IOT HVPS Capacitor bank Crowbar RF load Capacitor bank IOT RF load Our TX is probably capable to drive two IOT Still to be defined Two circulators to insulate IOT inputs ? Splitter with L3 configuration ? SSPA ? Drivers LVPS

Two IOT Drivers LVPS Schedule Cost IOT HVPS Capacitor bank Crowbar RF load Capacitor bank IOT RF load L3 does not want Thales/CPI to know about it (even NOT cern !) Thales already gave me a detailed sketch Drivers LVPS

Two IOT Drivers LVPS Schedule Cost IOT HVPS Capacitor bank Crowbar RF load Capacitor bank IOT RF load Second splitter should be ok Second set of loads has to be designed, tested and built (old supplier does not exist anymore), or to be bought Drivers LVPS
