CLIC is a world-wide collaboration to study the next “terascale” lepton collider, relying upon a very innovative concept of two-beam-acceleration. This accelerator, currently under study, will be composed of the subsequence of 21000 two-beam-modules. Each module requires more than 300 analogue and digital channels which need to be acquired and controlled in a synchronous way. CLIC-ACM is the custom control acquisition and control module which is being developed to concentrate all this signals in a single control point. This paper describes the system architecture with respect to its radiation-tolerance, power consumption and scalability.


CLIC-ACM, (Compact Linear Collider – Acquisition and Control Module) is a custom data acquisition system which is being developed to fulfil CLIC accelerator requirements. These requirements scope among reliability (in the sense of operational hours without beam time), radiation tolerance and power consumption. The data acquisition system under study will be adopting the GBTx implementation of Versatile link (developed at CERN by PH department) as main communication link. A full redundant star and an interleaved data acquisition of critical signal is proposed in order to improve system reliability.
In order to meet radiation-tolerance requirement flash based FPGA will be adopted and only radiation tolerant components will be used.
CLIC-ACM will be developed in a crate form factor were master and payload cards will be communicating over SLVS compliant links. The crate backplane topology is currently under study and will also be presented in this paper.
