	Funding: With contribution from EuCARD, Grant Agreement No:227579 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.
