	Under Indian Institutions and Fermilab collaboration Raja Ramanna Centre for Advanced Technology and Fermi Lab are jointly developing 2K Vertical Test Stand (VTS) cryostats for testing SCRF cavities. The VTS cryostat has been designed for a large testing aperture of 34 inches for testing of 325 MHz Spoke resonators, 650 MHz and 1.3 GHz multi-cell SCRF cavities for Project-X at FNAL and for VTS facility at RRCAT. VTS cryostat comprises of liquid helium (LHe) vessel with internal magnetic shield, top insert plate equipped with cavity support stand and radiation shield, liquid nitrogen (LN2) shield and vacuum vessel with external magnetic shield. . The engineering design and analysis of VTS cryostat has been carried out using ASME B&PV code and FEA. Design of internal and external magnetic shields was performed to limit the magnetic field inside LHe vessel, at the cavity surface <10 mG. Thermal analysis for LN2 shield has been performed to check the effectiveness of LN2 cooling.
