Proposal for the award of a contract for the supply of high-current bypass diodes for the LHC superconducting magnets

This document concerns the award of a contract for the supply of 2100 high-current bypass diodes for the LHC superconducting magnets. Following a price enquiry (DO-13258/LHC), long-term research work was launched by CERN in collaboration with three European firms which agreed to participate in the development of radiation-tolerant diodes for the protection of the LHC main dipole and quadrupole magnets. A call for tenders (IT-2723/LHC/LHC) was sent on 7 December 1999 to these three companies in two Member States. By the closing date, CERN had received three tenders. The Finance Committee is invited to agree to the negotiation of a contract with the firm DYNEX SEMICONDUCTOR LTD (UK), formerly MITEL SEMICONDUCTOR, the lowest bidder complying with the specifications, for the supply of 2100 high-current bypass diodes for the protection of the LHC main dipole and quadrupole magnets for a total amount of 714 736 pounds sterling (1 834 490 Swiss francs), subject to revision for contractual deliveries after 31 December 2001, with an option for the supply of up to 300 additional bypass diodes, for a total amount of 97 831 pounds sterling (251 100 Swiss francs), subject to revision for contractual deliveries after 31 December 2001, bringing the total amount to a maximum of 812 567 pounds sterling (2 085 590 Swiss francs), subject to revision for contractual deliveries after 31 December 2001. The above amounts in Swiss francs have been calculated using the rate of exchange stipulated in the tender. The firm DYNEX SEMICONDUCTOR LTD (UK) has declared the following origin of the equipment covered by this adjudication proposal: UK-79%, DE-9%, USA-12%.
