Power supply needs and main characteristics Recap of all the power supplies needed for Thom-X * 1 power supply for 4 sextupoles connected in series in order to reduce the costs Magnet Number Max Current (A) Max voltage (V) Power Supply Type Resolution (bits) Stability (ppm of Inom) Canon - Focalisation 1 400 55 Unipolar 12 ±55 Canon – Contre Champ 30 Dipole Ring 300 170 16 ±20 Dipole TL 85 Dipole EL 45 Dipole Inj TL- EL 2 18 Sextupole* 3 6 Quadrupole 38 Corrector Bipolar 15 + sign

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)

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).

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

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

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

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

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
