Anton Mezger - bio. Anton Mezger obtained his masters degree in 1982 in Solid State Physics. He then started work at the Paul Scherrer Institute (formerly SIN) as Crew Chief. He was rapidly involved in developing the accelerator control system and after 2 years he became Head of the Operations group (about 20 people). Over these last 16 years, he developed projects in various domains : data acquisition system software on the backends, most of the x-window display applications, periodic data gathering software and retrieval ("Logging"), Operator-Console processor, Control loops (PID), Interlock software system, ... After realising a first WEB based application allowing people to display periodically accelerator data through the WEB, he would like to replace the hand-written Operators Logbook with a WEB based application, which is the topic of the present session.
