The Superconducting Proton Linac (SPL) is an R&D effort conducted by CERN in partnership with other international laboratories, aimed at developing key technologies for the construction of a multi-megawatt proton linac based on state-of-the-art SRF technology, which would serve as a driver for new physics facilities such as neutrinos and radioactive ion beams. Amongst the main objectives of this effort, are the development of 704 MHz bulk niobium β=1 elliptical cavities, operating at 2 K and providing an accelerating field of 25 MV/m, and testing of a string of cavities integrated in a machine-type cryo-module. In an initial phase only 4 out of the 8 cavities of an SPL cryo-module will be tested in a ½ length cryo-module developed for this purpose thus called the Short Cryo-module. This paper presents the conceptual design of the Short Cryo-module, highlighting its innovative principles in terms of cavity supporting and alignment, and describes the integration of cavities and their main equipment (RF couplers, helium vessels, tuners, magnetic shielding) inside the cryo-module and their assembly method. The operational scenarios and test plans are also presented and discussed.

The Superconducting Proton Linac (SPL) is an R&D effort coordinated by CERN in partnership with other international laboratories, aimed at developing key technologies for the construction of a multi-megawatt proton linac based on state-of-the-art RF superconducting technology, which would serve as a driver for new physics facilities such as neutrinos and Radioactive Ion Beam (RIB). Amongst the main objectives of this R&D effort, is the development of 704 MHz bulk niobium β=1 elliptical cavities, operating at 2 K with a maximum accelerating field of 25 MV/m, and the testing of a string of cavities integrated in a machine-type cryomodule. The R&D program concerning the elliptical β=1 cavities fabricated from niobium sheets explores new mechanical design and new fabrication methods. The paper presents several opportunities for design optimization that were identified. A comparison between stainless steel helium vessel and titanium helium vessel including Nb to Ti transitions is addressed. Different mechanical design aspects, including cryogenic considerations, and fabrication aspects were analyzed and the results are discussed.
