Development Oversight • Design process conforms to FNAL Engineering Manual • The following documents are required to be approved prior to establishing a contract with the vendor: – Functional Requirements and Conceptual Design – Interface Control – Technical Requirements and Preliminary Design – Technical Verification Procedures (for amplifier modules and final amplifier) • Requirements list the following conforming standards: – Workmanship: IPC-A-610 E – Standards for PCBs: Lead free, IPC-A-600 – Environmental standards: ROHS Compliant – EMI/EMC standards: IEC-61204 -3; IEC 61010 -1 (safety rules) – Vibration standards for transportation only: IEC-61068 -27 & 64 7 26 -28 March 2018 James Steimel | In-kind Contribution: RF Power Amplifiers

Validation at ECIL • Vendor (ECIL) will produce first production model and verify the requirements. – This is a production hold point for amplifier construction. • FNAL experts and IIFC experts (BARC for 325 MHz and RRCAT for 650 MHz) will witness the testing process and results for the first production model of each type of amplifier. • Satisfactory approval of testing process and test results will constitute approval of final design for production. 8 26 -28 March 2018 James Steimel | In-kind Contribution: RF Power Amplifiers

Validation at Fermilab • IIFC and ECIL personnel will assist FNAL personnel with assembly of first, production amplifiers on site. • Testing will occur in dedicated testing lab (RF Lab in Booster Gallery, Meson Detector Building, New Muon Lab, etc. ) or at location of cryomodule if space is ready. • Testing unlikely to involve LLRF and RFPI system integration but remote controls integration will be tested. • IIFC and ECIL personnel will witness verification tests at FNAL for first production amplifiers. • After verification, amplifiers that are not tested in final place will be shipped to temporary storage for later placement. • FNAL personnel will continue to construct and test production amplifiers as delivered from ECIL. 9 26 -28 March 2018 James Steimel | In-kind Contribution: RF Power Amplifiers

Integration in PIP-II • Amplifiers will be re-assembled into place once gallery space is occupational. • Circulators and directional couplers will be connected with necessary coaxial hardline. • LLRF system, RFPI system, external interlocks, water, AC power, and controls will be connected. • Each integrated system will be tested with full power through the circulator and into a load to verify amplifier performance, test interlocks, and verify controls and instruments. • Connection of RF distribution to cryomodule couplers is one of last steps of construction in the beam line enclosure. 10 26 -28 March 2018 James Steimel | In-kind Contribution: RF Power Amplifiers

Redundancy Plans • 7 k. W, 325 MHz RF power amplifiers are available on the international market. • If BARC successful with construction of 20 k. W, 325 MHz RF power amplifier, it would be possible to have them modify amplifier design to accommodate 650 MHz and combine outputs for 40 k. W. • Likewise, if RRCAT successful with construction of 40 k. W, 650 MHz RF power amplifier (already the combination of 20 k. W units), it would be possible for them to modify 20 k. W design to accommodate 325 MHz. • If no collaborators can produce high power amplifiers, we would look into quotes for IOT based power amplifiers. 15 26 -28 March 2018 James Steimel | In-kind Contribution: RF Power Amplifiers

Risk Management Approach • Risk register assumes a moderately high probability (50%) that the amplifiers will require some minor modifications upon delivery with a total cost limit <$500 k for the project. • Beyond this price level, the amplifiers are assumed to be non -functional and must be returned for re-work. • Risk of failure to deliver amplifiers not carried by the project. 16 26 -28 March 2018 James Steimel | In-kind Contribution: RF Power Amplifiers

Summary • IIFC collaborators and vendors have proven technical expertise in design and construction of solid state power amplifiers. • Design reviews and oversight following FNAL Engineering Manual procedures. • Collaborators have agreed to comply with international standards for quality and safety. • Integration plans are already taking shape. • Multiple levels of risk mitigation and exposure reduction have been identified. 17 26 -28 March 2018 James Steimel | In-kind Contribution: RF Power Amplifiers
