The document typically outlines what is needed by the end user as well as the requirements and requested properties of inputs and outputs. The FRS specifies the functions that a system or component must perform and establishes consensus among stakeholders on what the system is expected to provide.ScopeThe PIP-II MEBT beam optics assumes that the chopping scheme includes 2 travelling-wave kicker structures working synchronously. The kicker electric field is generated by applying equal and opposite polarity voltage to the two opposing electrodes of each kicker structure.In this FRS, the mechanical components (vacuum chamber, electrodes, loads) and the electronics (driver) together define a “kicker assembly”. The “kicker system” refers to the combination of the two kicker assemblies operating together. This FRS addresses the functional requirements of the PIP-II MEBT kicker system and of the kicker assemblies. The main inputs to/outputs from the kicker assemblies for the kicker system to operate are also specified. This FRS does not include specifications of stands for installation of the kicker assemblies in the beam line.AcronymsCWContinuous WaveFESHMFermilab ES&H ManualFRCMFermilab Radiological Control ManualFRSFunctional Requirements SpecificationL2WBS Level 2L3WBS Level 3LLRFLow-Level Radio-FrequencyMEBTMedium Energy Beam TransportMPSMachine Protection SystemPIP-IIProton Improvement Plan II Project RFRadio-FrequencyRFQRadio-Frequency QuadrupoleSCDSystem Configuration DocumentTCTeamcenterWBSWork Breakdown StructureWFEWarm Front EndReference#ReferenceDocument #1PIP-II MEBT Kicker EPDMED00012712Installation and Commissioning (WBS 121.4) System Configuration Document (SCD)ED000xxxx3Fermilab Engineering ManualN/A4Fermilab Environmental Safety and Health ManualN/A5Fermilab Radiological Control ManualN/AKey AssumptionsThe time structure of the beam pulse entering the MEBT is consistent with the requirements of bucket-to-bucket injection into the Booster ring i.e. 5 mA, 0.55 ms-long pulses at 20 Hz. The beam energy is 2.1?MeV ±1% (? = 0.0668).Specifications for the electrical power distribution and water cooling are beyond the scope of this document.Functional RequirementsRequirement #Requirement StatementF-121.4.02.02.01.XX-001The angular deflection of the trajectories between bunches assigned for removal and those passing shall be 7.4 mrad ±10% per kicker assembly.F-121.4.02.02.01.XX-002Each kicker assembly shall deflect the beam in the vertical direction.F-121.4.02.02.01.XX-003The kicker system shall be able to let pass or remove any of the 162.5?MHz bunches delivered by the RFQ according to a pattern driven by the LLRF system that accommodates bucket-to-bucket injection into the Booster ring.F-121.4.02.02.01.XX-004Each kicker assembly is contained between two quadrupole triplets (i.e. transverse focusing stations).F-121.4.02.02.01.XX-005The kicker structures shall withstand steady-state irradiation (CW) from the tails of the H- beam as well as accidental beam loss distributed along all individual electrodes on one side of the kicker structure.F-121.4.02.02.01.XX-006Each kicker assembly shall incorporate two electrically isolated plates to protect the kicker from accidental beam scraping (a.k.a. masks).
