INTEGRATION DES ALIMENTATIONS REX-ISOLDE OBJECTIFS AB/PO Processus identique à celui d’ISOLDE et OFF-LINE Définir des noms d’opération officiels. (appellation commune OP, CO, PO, utilisateurs) Rationaliser les équipements. Prendre en compte la sécurité industrielle. Adapter les interfaces de contrôles. (conforme à la division AB) Réaliser les documentations nécessaires. Elargir les connaissances à l’intérieur du groupe PO, pour faciliter l’exploitation. Améliorer les possibilités condamnation- décondamnation. Prendre en charge l’exploitation par l’équipe de piquet PO (futur) 23/06/2004 N.David - AB/PO/PH J-P ROYER AB/PO

Over view - Converters Complexity machine with few different elements. 146 converters for 34 different types. 2 family of converters (alimentation # amplifier). Diversity of converters : 200V to 65kV and 2A to 350A. Very little compatibility with ISOLDE or AB-PO. Electrical distribution problems (lock, separate an equipment). Location of some racks of converters (TRAP-EBIS). 2 programmed references/acquisitions systems for EBIS, 1 for TRAP (ask an homogenization of control system). Space for automates, exotic automates crates (control). Ratio=4.3 contre 18.3 pour ISOLDE, 4.4 AD… 23/06/2004 N.David - AB/PO/PH

Over View – Converters Spares 34 different types of converters 12 types with operational spares 35% of REX have spares : very bad 23/06/2004 N.David - AB/PO/PH

Over View – Critically elements TRAP Section : - 8 Amplifiers REXTRAP +/-200V : no spare EBIS Section : - 1 Pulsed alimentation FUG 22kV => 60kV : no spare and broken once. - 2 Amplifiers TREK 601-4B +/-500 : no spare and broken once. SEPARATOR Section : - 1 Alimentation DC Bouhnik AF99032 (20V/60A). - 7 Alimentations Brandenburg 590 (+ et – 7.5kV). LINAC Section : - 19 Alimentations Danfysik 858 (160A, 180A, 200A et 220A => 4 # groups). - 4 Alimentations Danfysik 896 (±35V/±10A): 2 are broken (replaced by 1 Heidelberg). - 3 Alimentations Heidelberg (±20V/±2A) with same functions as Danfysik 896 - 1 Alimentation Bruker MN65/352 (65V=>350A) Control Section : - Automate crate are not same for all or are not in crate, few manufacturers… 23/06/2004 N.David - AB/PO/PH

Short term solutions A stock of spares/components must be created for critical elements : - Fug 22kV - 60kV EBIS : must obtain 1 spare for control crate or 1 additional converter (~23KCHF for control crate, 120KCHF for converter). Already, we have critical components for control crate. Danfysik 858 : we must get sufficient spares of components/cards (~ 4KCHF) - Bouhnik AF99032 : a spare must be done with a Danfysik 896 model (~8KCH) or by an other way. - 2 TREK 601-4B : must be replaced by TREK 601-2C (~ 4x6.5KCHF) or by a modular system or a hybrid enclosed system (~8x2KCHF) - LMU REXTRAP : must create 1 spare module or be replaced by same modular system as TREK601-4B (~8x2KCHF) - Brandenburg + et – 7.5kV : 3 spares elements must be ordered (~4800 CHF) or be replaced by Heinzinger LNCE6000-1 model (~13x1KCHF) … Tests benches must be created for tests and future repairs. 23/06/2004 N.David - AB/PO/PH

Long term solutions Converters types must be rationalized to AB-PO : - 4 crates with cards 24DC3500 : must be transformed in same type as ISOLDE (~4x3000CHF). - 12 Fug HCE-7 : type to be replaced by Fug HCN-7 type (~12x2300 CHF). - Spares for Fug HCE-35 must be ordered (~3x2500 CHF). - Danfysik 896/Heidelberg converter : we must choose 1 converter type and buy this type to replace the other type (?CHF). - 2 TREK 601-2C : be replaced by modular or hybrid system, same as TREK601-4B (~4x2KCHF). … Electrical must be reorganized, ISOLDE distribution crates must be added for all racks (? 30KCHF). Some converters must be delocalized, RA0 and Ion source converters, regroup free mounted converters of TRAP 3 crates & 2 converters (?CHF). Some automates must be integrated in crates and a rationalization between crate must be done, with AB/CO group (?CHF). 23/06/2004 N.David - AB/PO/PH

Works in realizations Find and create denominations for new or unnamed REX elements, and doing modifications in order to label each converters. Create stock of spares components/cards for critical converters. Quote request/estimation for spare components or spare converters. Find all documents in relation with REX converters. Make test bench for modular converters : LNCE6000-1, DC24-35000, 700V, Brandenburg 590… Investigate for replacement of TREKs low voltage and REXTRAP modules (searching for a common element). Search for other possible solutions in future rationalization. … 23/06/2004 N.David - AB/PO/PH

Contribution to ameliorate the reliability of the REX machine Conclusions For exploitation : - Converters types must be reduced. - Standardization/rationalization of types. - Components/elements spares for all types. - Modifications must be scheduled. Indispensable budget : - Converters are very expensive things. - Today, estimation is over 300 KCHF without control. - Costs for the modifications must be scheduled. Necessary to modify, improve, standardize, reorganize or readapt controls interfaces according with AB/CO group. All treatments must be invisible for the beam (increase performance and decrease complexity). Contribution to ameliorate the reliability of the REX machine 23/06/2004 N.David - AB/PO/PH
