In 1954 - as a formal result of an agreement within twelve nations in Europe - CERN was established. The principle aim was to create an efficient collaboration between the member institutes working on the field of particle physics and support their research work with a complex accelerator system.

The LHC (Large Hadron Collider) maintained by CERN with its 27 km perimeter is the largest particle accelerator in the world. As one of the main experiments at CERN, the ALICE (A Large Ion Collider Experiment) - among the others - is supplied by the LHC. The ALICE is mainly devoted to investigate the quark-gluon plasma based on the outcome of ion collisions. The results of interactions are measured by complex detector systems and recorded by powerful computers.

In highlight of recent results, a new extension of ALICE become desired in order to identify particles in the 5 -- 25 GeV/c transverse momentum range. The VHMPID (Very High Momentum Particle Identification Detector) and HPTD (High Pt Trigger Detector) detectors are designed to fulfill this requirement.

The object of my Thesis is the design and development work of a front-end electronics, which is capable of integrating the HPTD detector into the ALICE experiment.

In the first part of my study, I briefly present the goals of ALICE and introduce the VHMPID and HPTD detectors. The relevant parts of the high-level data acquisition and trigger systems are also discussed.

The second part of my report contains the detailed description of the design work. The different levels of implementation (system level, block level, etc.) are organized into separated sections.

Finally, I enclose technical details regarding the manufacturing of prototype circuit including the schematics, PCB drawings and list of materials.
