    "abstract": "Some modifications of a Rectangular Waveguide HOM couplers for TESLA\nsuperstructure have been investigated. These RWG HOM couplers are to be\ninstalled between the cavities of the superstructure and also at the both ends\nof it. We investigated a RWG HOM coupler attached to the beam pipe through the\nslots orientated along beam pipe axis (longitudinal slots), perpendicular to it\n(azimutal slots) and at some angle to this axis. For dipole modes of both\npolarizations damping two RWG in every design were used. This paper presents\nthe results obtained for scaled-up setup at 3 GHz at room temperature. The\nadvantages of HOM coupler with longitudinal slots for damping dipole modes and\ncompact HOM coupler with slots at some angle to the axis are shown. Arrangement\nof HOM coupler in cryostat and heating due to HOM and FM losses are presented.\nCalculations and design of the feeding RWG coupler for superstructure are also\npresented.",
