This paper describes the JINR design of the large 2 T superconducting solenoid for the target spectrometer of the PANDA experiment at HESR (FAIR, GSI, Darmstadt, Germany). The solenoid coil has an inner radius of 1.08 m and a length of 2.90 m. This solenoid is non-centrally split providing a warm bore of 100 mm in diameter through the coil to accommodate sufficient space for the internal target installations. Maximally stored energy in the windings is 22.3 MJ. All tracking and calorimetric detectors surrounding the target point, with exception of a forward cone of e=""mml41"">e=""text-decoration:none; color:black"" href=""/science?_ob=MathURL&_method=retrieve&_udi=B6TJM-4R6B2CR-1&_mathId=mml41&_user=10&_cdi=5314&_rdoc=12&_acct=C000050221&_version=1&_userid=10&md5=ccf4e35e14c303d63ac3934a73a00821"" title=""Click to view the MathML source"">5![]()

The main features of the design and technique are as follows: a copper stabilizer and soldering technique for the superconducting cable; a stainless steel cryostat; winding technique over a mandrel; coreless type of the coil; low operational current. The details of the PANDA solenoid design including the magnetic field and stress–strain calculations are covered.
