HIGH POWER AMPLIFIERS For WARM LINAC Arash Kaftoosian ESS Bilbao, May 2018

Outline SSPA for MEBT Status Klystron Driver Amplifiers Re-conditioning/Repair of 3 existing klystrons Tendering Process of the 3 new klystrons

STATUS OF SSPA TENDER 3 x 30kW solid-state amplifiers for feeding buncher cavities in MEBT Tender published in March with closing date on 23/4/2018 5 offers received: BTESA and TTi from Spain, DB Science and SYES form Italy, TMD from the UK Only two companies (BTESA and TTi) provided required administrative documents and could pass to technical evaluation stage. Technical evaluation is in process and June 15th the third envelop which includes the offered price will be opened and the winner will be determined.

TIME SCALE OF SSPA July18 April19 October19

DRIVER AMPLIFIERS

DRIVER AMPLIFIERS Call for tender: 6 x 500W 352MHz RF amplifiers as klystron driver. Question: Should we add 1 or 2 driver units to the tender as spare units, under the “Scope swap” scheme? All documents are ready to publish the tender Call for tender is expected to be out in June

DRIVER TIME SCALE July18 Dec.18 May19 First Amplifier Delivery CDR SAT First Amplifier Delivery ValidationApproval (SAT) 2nd to 6th Amplifiers Delivery Signing Contract

KLYSTRONS Three out of four VKP-8352A klystrons from CPI are being prepared to send to Lund Three new klystrons to be procured (Call for tender in June)

EXISTING KLYSTRONS Re-conditioning of 2 klystrons VKP-8352A SN#002 and #004 is ongoing at ESS-Bilbao test stand and expected to be finished in Q3/Q4 this year

EXISTING KLYSTRONS Klystrons VKP8352A SN#001 and #003 are ready to ship to CPI, Palo Alto Klystron #003 has a microleak in vacuum system and will be repaired at CPI Klystrons will be tested and conditioned for long RF pulse, plus warranty extension procedure Depends on the timing, first three klystrons that are ready, will be shipped to Lund (either form Bilbao or from Palo Alto)

NEW KLYSTRONS PROCUREMENT Technical specification (SoW) and administrative documents for 3 new klystrons are ready and call for tender is to be published in June. The delivery schedule is foreseen as below: July18 July19 Oct.19 Jan.20 0m 2m 12m 15m 18m 20m Kickoff Meeting 1st klystron FAT and ship out 2nd klystron FAT and ship out 3rd klystron FAT and ship out Signing Contract Design Review Validation Approvals (SATs)
