  With aging hard­ware and ex­pen­sive main­te­nance and re­place­ment pos­si­bil­i­ties, it was de­cided to up­grade the CERN An­tipro­ton Ac­cu­mu­la­tor Com­plex (AAC) touch ter­mi­nal con­soles with mod­ern hard­ware. With sig­nif­i­cant amount of op­er­a­tional ap­pli­ca­tion soft­ware de­vel­oped with touch ter­mi­nals over 10 years, the phi­los­o­phy adopted was to at­tempt a total em­u­la­tion of these con­sole func­tions of touch ac­tions, graph­ics dis­play as well as sim­ple key­board ter­mi­nal entry onto the front-end com­puter con­trol­ling the AAC. The PC based em­u­la­tion by mouse and mul­ti­ple win­dows under MS-DOS and later, under the Win­dows 3 en­vi­ron­ment was re­al­ized rel­a­tively quickly; the next stage was there­fore to do the same on the Unix plat­form using soft­ware based on X-Win­dows. The com­mu­ni­ca­tions chan­nel was es­tab­lished using the TCP/IP socket li­brary. This paper re­views this work up to the op­er­a­tional im­ple­men­ta­tion for rou­tine con­trol room usage for both these so­lu­tions.

  Schot­tky sig­nals are ex­ten­sively used for ob­ser­va­tion, set­ting-up and op­er­a­tion of CERN’s An­tipro­ton rings, namely the AC, the AA and LEAR. Mea­sure­ment of these sig­nals is, at pre­sent, car­ried out by a se­ries of com­mer­cial in­stru­ments. These in­stru­ments have to be in­di­vid­u­ally con­trolled and read by each ap­pli­ca­tion pro­gram. The op­er­a­tional use of the sys­tem is lim­ited by the ca­pa­bil­i­ties of the in­di­vid­ual in­stru­ments. The first ob­jec­tive for the new sys­tem was to pro­vide, as far as pos­si­ble, a true "server". The "client" ap­pli­ca­tion pro­gram sim­ply re­quests the data it re­quires. It is then sup­plied with mea­sured and processed data. This pro­vides the op­er­a­tor with a fast re­sponse by hav­ing ready processed data al­ways avail­able. Our sec­ond goal was to make the sys­tem op­er­a­tionally sim­ple, with mul­ti­ple win­dows and pre­sen­ta­tion on a sin­gle screen. This paper dis­cusses some as­pects of this im­ple­men­ta­tion and ap­pli­ca­tions for the an­tipro­ton pro­duc­tion, col­lec­tion, and stor­age rings.
