INTEGRATION DES ALIMENTATIONS REXISOLDE OBJECTIFS ABPO Processus identique

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.

Over view - Converters • • Complexity machine with few different elements. 146 converters for 34 different types. 2 family of converters (alimentation # amplifier). Diversity of converters : 200 V to 65 k. V and 2 A to 350 A. 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). 23/06/2004 N.

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 +/-200 V : no spare EBIS Section : - 1 Pulsed alimentation FUG 22 k. V => 60 k. V : no spare and broken once. - 2 Amplifiers TREK 601 -4 B +/-500 : no spare and broken once. SEPARATOR Section : - 1 Alimentation DC Bouhnik AF 99032 (20 V/60 A). - 7 Alimentations Brandenburg 590 (+ et – 7. 5 k. V). LINAC Section : - 19 Alimentations Danfysik 858 (160 A, 180 A, 200 A et 220 A => 4 # groups). - 4 Alimentations Danfysik 896 (± 35 V/± 10 A): 2 are broken (replaced by 1 Heidelberg). - 3 Alimentations Heidelberg (± 20 V/± 2 A) with same functions as Danfysik 896 - 1 Alimentation Bruker MN 65/352 (65 V=>350 A) Control Section : - Automate crate are not same for all or are not in crate, few manufacturers… 23/06/2004 N.

Short term solutions • A stock of spares/components must be created for critical elements : - Fug 22 k. V - 60 k. V EBIS : must obtain 1 spare for control crate or 1 additional converter (~23 KCHF for control crate, 120 KCHF for converter). Already, we have critical components for control crate. - Danfysik 858 : we must get sufficient spares of components/cards (~ 4 KCHF) - Bouhnik AF 99032 : a spare must be done with a Danfysik 896 model (~8 KCH) or by an other way. - 2 TREK 601 -4 B : must be replaced by TREK 601 -2 C (~ 4 x 6. 5 KCHF) or by a modular system or a hybrid enclosed system (~8 x 2 KCHF) - LMU REXTRAP : must create 1 spare module or be replaced by same modular system as TREK 601 -4 B (~8 x 2 KCHF) - Brandenburg + et – 7. 5 k. V : 3 spares elements must be ordered (~4800 CHF) or be replaced by Heinzinger LNCE 6000 -1 model (~13 x 1 KCHF) … • 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 24 DC 3500 : must be transformed in same type as ISOLDE (~4 x 3000 CHF). - 12 Fug HCE-7 : type to be replaced by Fug HCN-7 type (~12 x 2300 CHF). - Spares for Fug HCE-35 must be ordered (~3 x 2500 CHF). - Danfysik 896/Heidelberg converter : we must choose 1 converter type and buy this type to replace the other type (? CHF). - 2 TREK 601 -2 C : be replaced by modular or hybrid system, same as TREK 601 -4 B (~4 x 2 KCHF). … • Electrical must be reorganized, ISOLDE distribution crates must be added for all racks (? 30 KCHF). • Some converters must be delocalized, RA 0 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 : LNCE 6000 -1, DC 24 -35000, 700 V, 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

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).
