5. Power supply needs and main characteristics
To optimize costs and spare part stocks:
1 type of power supply for the sextupoles, the quadrupoles and the correctors
1 type of power supply for the TL Inj Dipole PS + DL Inj Dipole PS
Allocation in 6 cabinets 600(W)* 800(D)* 2000(H)
Cabinets for the dipole power supplies:
Ring Dipole PS : 1 cabinet 800(W)* 1000(D)* 2000(H)
TL-EL Dipoles PS : 1 cabinet 800(W)* 1000(D)* 2000(H)
1 Cabinet for the focalisation solenoid power supplies of the RF gun:
Focalisation & contre champ PS : 1 cabinet 800(W)* 1000(D)* 2000(H)
And notably the CPCI crate (dedicated to PS remote control)

6. Power supply needs and main characteristics
NB : One extra cabinet (600(W)* 800(D)* 2000(H)) for the magnet interlock system and the additional quadrupole & corrector power supplies for the EL and the Linac (which have been purchased after the initial call for tenders).

7. Control system Hardware architecture:
All the power supplies will be interfaced to a Compact PCI crate (hosting Profibus & CPU cards) via a Profibus DP fieldbus (idem SOLEIL)
Software bus: TANGO
Corba based control system developped by ESRF/SOLEIL
Mature and well-tested
Code developped at SOLEIL may be re-used for THOM-X

8. Activity report of 2016
Tests of the 78 power supplies (Quadrupoles, Sextupoles, and Correctors) from « lot 2 » in order to check the specifications, mainly in terms of stability and resolution
Stability :
Requested : ±20ppm = 480µA
Stability : 200µA ∼ 17ppm

9. Activity report of 2016
Resolution
Adding of an interlock on the dipole PS (Ring-TL-EL) for the PSS
Study of the electrical distribution and modification of cooling water circuits for the focalisation solenoids power supplies of the RF gun
New cabinet layout to integrate the lately purchased power supplies
Requested : 16bit  185µA
Measured : < 150µA

10. Activity report of 2016
Test and validation of the PS remote control at Soleil
Configuration of the hardware architecture of the Profibus DP fieldbus
Test of the TANGO Dservers interfacing the power supplies
Preparation of the spares list for all the power supplies
Training of LAL personnel

11. Remains to be done
Integration of the new power supplies in the additionnal cabinet
Completion of cabinet for the focalisation solenoids power supplies of the RF gun
On-site installation of the PS cabinets, cabling of the power supplies, on-site tests (power + remote control)
Thank you for your attention
