| Abstract | A liquid hydrogen target has been developed for the COMPASS experiment at CERN. The target has a diameter of 40 mm and a length of 2.5 meter, creating an active volume of about 3 liter of liquid hydrogen. The cylindrical part of the target wall is formed by a Kapton® foil strip, wound and glued to a thickness of 0.125 mm. The Kapton® foil is used to minimize the energy loss of the particles, scattered or created within the target volume, crossing the target boundary. The two end-caps enclosing the target volume have been fabricated from Mylar®. The system is cooled with a 30 W at 20 K cryocooler, delivering the cooling capacity for the cool-down as well as for the continuous operation of the system. |
