HISTORICAL PAGES
SINCE 1994 WE ARE WORKING
ON THE PREPARATIONS OF THE HV POWER SUPPLY
FOR TILECAL ATLAS CALORIMETER IN CERN. FIRST
POWER SUPPLY FOR A TEST WAS
BUILT IN THE DEPARTMENT OF ELECTRONICS OF
INSTITUTE OF PHYSICS, PRAGUE IN 1994.
THEN THERE WAS BUILT WORKING SAMPLE - PREPROTOTYPE IN TESLA COMPANY. THIS
PREPROTOTYPE WAS PRESENTED AND TESTED IN CERN
IN 1995 AND UP TO NOW IS USED
FOR THE TESTS OF CALORIMETER ELECTRONICS.
THERE WERE MEASURED PARAMETERS OF THIS PREPROTOTYPE AND THIS POWER SUPPLY
DESIGN WAS CONFIRMED AS ABLE TO WORK DURING
PRR PROCEDURE. THEN THERE WERE
PREPARED ALL DOCUMENTS FOR MARKET SURVEY ,
ESPETIALLY TECHNICAL SPECIFICATION,
BASED ON THE EXPERIENCE WITH PREPROTOTYPE.
AFTER MARKET SURVEY THE
WINNER TESLA COMPANY BUILT THE PROTOTYPE EQUIPED
BY ALL CHANNELS AND WITH FULL EQUIPMENT
NEEDED FOR A WORK ON ATLAS.
IN THE DEPARTMENT OF ELECTRONICS WE BUILD
SPECIAL TESTBED FOR MEASUREMENTS
OF THE POWER SUPPLIES WHICH WILL BE PRODUCED. WHOLE HISTORY
IS ALSO VISIBLE FROM THE PRESENTATIONS ON THE COLLABORATION MEETINGS OR OTHER PRESENTATIONS.
