TE-EPC internal review of the ELENA project ELENA sub-work package 2. 4. 5 José Manuel de Paco 5 th November 2015

Deliverables of ELENA WP 2. 4. 5 Controls for HV Power Converters: Electrostatic Transfer Lines José M. de Paco (CCS) Christophe Machado (FPC) • Control System: • Front-End Computer • Front-End Software: FGCD. • PLC-based interlock system • Vacuum interlocks • Interlocked Power Supplies (IPS) • One rack for its installation 5 th November 2015

Deliverables of ELENA WP 2. 4. 5 Controls for HV Power Converters: Ion Switch José M. de Paco (CCS) Christophe Machado (FPC) • Control System: • PLC system to control FUG power converters (installed in rack for ion switch). • Front-End Software. 5 th November 2015

Definition and approval of ELENA WP 2. 4. 5 • Electrostatic Transfer Lines and Electron Cooler • Currently writing a functional specification. • Ion switch Powering • Specifications under discussion. 5 th November 2015

Purchasing strategy of ELENA WP 2. 4. 5 • Electrostatic Transfer Lines and Electron Cooler • To be done soon: FEC request to BE-CO. • Interlocks PLC order to Siemens (depending supplier proposal). • Ion Switch • PLC system: CPU and IO Modules already purchased. 5 th November 2015

Testing strategy of ELENA WP 2. 4. 5 • Lab testing before commissioning for all the control systems. 5 th November 2015

Installation strategy of ELENA WP 2. 4. 5 • Done: • Ethernet sockets requested. • Timing cables requested. • To be done: • PLC systems (ion switch and interlocks) will be installed in a crate and installed in ELENA platform after testing in lab. • Cabling distribution between interlock PLC and power converters. • Installation of FEC in the control rack. • Connection of the commercial chassis systems to the Technical Network after their installation. • In charge: Jose M. de Paco (CCS), Christophe Machado (FPC), Christophe Coupat (OMS). 5 th November 2015

Overall status of ELENA WP 2. 4. 5 • Status: • Writing functional analysis. • Software development will start with the reception of ISEG test power converters. • Ion switch control system depends on specification and definitive design. • Planning: • • • November 2015: functional specification approval, first SW developments. December 2015: functional specification approved. April-May 2016: lab testing. June-July 2016: commissioning. Spending Profile (budget code 99292): Before 2015 (CHF) - 2015 (CHF) 2016 (CHF) Total (CHF) 28 000 72 000 100 000 5 th November 2015

Open points of ELENA WP 2. 4. 5 Electrostatic Transfer Lines • Functional specification to be approved. • Operation mode: DC. But some elements may need to switch to 0 V (interleaved cycles AD – source). • Risk: new development, delay. Ion switch • Need of specification of Ion-switch and switch box. • Interleaved cycles AD – source: switching times. • Risk: delay, dependence on chosen solution. Mitigation: use of FUG cassettes and manual switching during commissioning. Electron Cooler • Missing specification. • Risks: change of specifications, delay. 5 th November 2015
