Interlocks controls power supplies and ancillaries in PSB

Interlocks, controls, power supplies and ancillaries in PSB Actual system for the PSB tests And proposed evolution for the final system

SUMMARY Present system short description Proposal for final hardware solution Cost

Present system short description Small standalone PLC (Programmable Logic Controller) to perform the sequencing task, interlock, monitoring and local control. Expected PLC cycle 1 to 2 msec , ok for interlocks Local values display and logging Estimated PLC rack space 11 U

Present system short description Signals and interlocks monitored Water cooling: Control (Open/Close Valves) Temperature and flow monitoring Cavity (one Gap): Two temperatures left and right Interlocked Power supply: Model TDK Lamda GEN 40 -125 (2 x 0. . 40 V 125 A) Control ON/OFF Voltage and current monitoring also routed to local monitoring for oscilloscope connection Amplifier: Fuse presence Thermal switch chain Mosfet Compensation Status Current monitoring distribution

Present system short description PLC sequence

Proposal for final “hardware” solution The final system will be composed of 6 RF systems of 6 gaps each a total of 36 gaps per booster ring. The 36 gaps will be considered as one cavity, seen from operation point of view, with possibility of disabling a number of gaps. The proposed solution is based on modern PLC (programmable logic controllers) inspired form the recent AD and SPS amplifier control renovation. PLC I/O 12 power supplies

Proposal for final “hardware” solution

Proposal for final “hardware” solution Details of the links between the different components of the system for Cavity of Ring 1 Monitoring of total power supply current Amplifier status Monitoring of individual mosfets current and amplifier status Cavity temperatures Infrastructure: One complete control system for a 6 gap module will be provided at the RF 6 GAP Amplifiers test place. power cables All the racks, 24 in total, will be identical they can be constructed and tested in the test place before installation.

Proposal for final “hardware” solution The local control for one cavity will be available trough a touch screen in one of the BRF 1 racks Ex: PS 80 MHz cavity local control The remote control and monitoring will be integrated in the CERN standard SILECS/FESA/INCA framework that provides controls, monitoring and alarms. Ex: SPS 800 MHz cavity remote control

Cost and procurement The control system procurements will include: All PLC I/O, CPU and accessories for the machine plus one complete system for the test place. All parts to build all the chassis. FSU manpower for construction, test and installation. Will not included: Cables, connectors and cable installation. Cost estimation (see M. Paoluzzi presentation) Planning: Final system design by mid 2016 => this requires power supply model to be defined Test place ready for power test by end 2017 Final systems procurements, production and test during 2018 Installation during ½ LS 2 (2019)
