1. Способ бесконтактного измерения критического тока ВТСП, при котором по катушке соленоида пропускают постоянный возрастающий ток - создают магнитное поле, которым в ВТСП-кольце возбуждают экранирующий ток, измеряют ток соленоида и напряжение датчика Холла, строят их графическую зависимость, по которой определяют величину критического тока, отличающийся тем, что величину критического тока определяют по разности полей соленоида без ВТСП-кольца и с ВТСП- кольцом на линейном участке графика зависимости напряжения Холла от тока соленоида, где поле соленоида, не проникающее в объем кольца, не влияет на его критический ток.1. A method of contactless measurement of the critical current of an HTSC, in which a constant increasing current is passed through the coil of a solenoid — create a magnetic field by which a screen current is excited in the HTSC ring, measure the solenoid current and voltage of the Hall sensor, construct their graphical dependence, which determines the critical value current, characterized in that the critical current value is determined by the difference of the fields of the solenoid without the HTSC ring and with the HTSC ring in the linear section of the graph of the dependence of the Hall voltage on the current of the solenoid, where the solenoid field, which does not penetrate the ring volume, does not affect its critical current. 2. Устройство бесконтактного измерения критического тока ВТСП, содержащее соленоид с магнитомягким сердечником и датчиком магнитного поля, отличающееся тем, что магнитный сердечник является магнитозамкнутым, состоит из двух частей, на участке внутри соленоида имеет зазор, в котором располагается датчик поля, а на соленоид на уровне датчика поля надето ВТСП-кольцо.2. A non-contact HTSC critical current measurement device containing a solenoid with a soft magnetic core and a magnetic field sensor, characterized in that the magnetic core is magnetically closed, consists of two parts, in the area inside the solenoid there is a gap in which the field sensor is located, and on the solenoid The level of the field sensor is wearing a HTSC ring.
