  All particle accelerators and most experiments at CERN require high (HV) or ultra-high (UHV) vacuum levels. Contributing to vacuum production are two types of mobile devices: Turbo-Molecular Pumping Groups and Bakeout Racks. During accelerator stops, these PLC-controlled devices are temporarily installed in the tunnels and integrated in the Vacuum SCADA, through wired Profibus-DP. This method, though functional, poses cer-tain issues which a wireless solution would greatly miti-gate. The CERN private LTE/3G network is available in the accelerators through a leaky-feeder antenna cable which spans the whole length of the tunnels. This paper describes the conception and implementation of an LTE/3G-based modular communication system for PLC-controlled vacuum mobile devices. It details the hardware and software architecture of the system and lays the foun-dation of a solution that can be easily adapted to systems other than vacuum.

  Linac4 is 160 MeV H linear accelerator replacing Linac2 as the first injector to the CERN accelerator complex, that culminates with the Large Hadron Collider. This new linac will increase the beam brightness by a factor of two. The vacuum installation consists of 235 remotely controlled pumps, valves and gauges. These instruments are either controlled individually or driven by pumping stations and gas injection processes. Valves and pumps are interlocked according to gauge pressure levels and pump statuses. The vacuum control system communicates with the beam interlock system, the ion source electronics and the Radio Frequency control system, through cabled digital and analog signals. The vacuum control system is based on commercial Programmable Logical Controllers (Siemens PLCs) and a Supervisory Control And Data Acquisition application (Siemens SCADA: WINCC OA). This paper describes the control architecture and process, and reports on the control requirements and the implemented solutions.
