摘要： PURPOSE:To make it possible to perform an automatic orbit adjustment by executing the adjustment of a deviation of particle beams orbit while mimizing the exciting power of a correcting electromagnet. CONSTITUTION:Particle beam positional signal DELTAr1-DELTAr4 from beam monitors M1-M4 are input into an automatic orbit controller 2. Based on the current command of the automatic orbit adjusting device 2, correcting electromagnets S1-S3 are excited by power controllers 31-33. The correction of an orbit deviation to microchange in a current command which is a basic data of orbit correction is sequentially carried out in all of the correcting electromagnets S1-S3 and a correcting current command value to the orbit deviation is reversely operated based on the resultant data. Since all of the current command values can not be actually obtained based on only the data, in order to minimize the effect to the correction beams, the current command value is determined by adding the condition in which the sum of electromagnetic energy of the correcting electromagnet is minimized. Thus, it is possible to optimize the automatic adjustment of the particle orbit of the accelerator.

摘要： PURPOSE:To control the current distribution of a helical coil arbitrarily by constructing the helical coil of a plurality of windings and by providing each winding with a discrete power source for excitation. CONSTITUTION:A plasma 1 is maintained in a vacuum vessel 2 by a contained magnetic field generated by a helical coil 3. Since the helical coil 3 is composed of discrete windings 31 to 35, the position of the center of an exciting current can be varied by controlling a current of each winding. In the case when the windings 34 and 35 of two layers inside the helical coil 3 are electrified, for instance, the position of the center of the exciting current is shifted near to the plasma and therefore the plasma 1 becomes small. The plasma 1 becomes large, to the contrary, when the windings 31 and 32 of two layers outside the helical coil 3 are electrified. According to this constitution, it is possible to execute such an operation as to make the plasma small when it is made to rise, and to shift it into a steady state after it rises stably.

摘要： PURPOSE:To protect a fusion device utilizing an attenuation of a plasma electric current by placing the first position and shape detector of a plasma section, along a toroidal direction and the second one at a point having an angle of 90 deg. against the direction, and by comparing signals from the two detectors. CONSTITUTION:A protecting device 6 has an accumulator 61 which accumulates signals from detectors 3, 4 and so on, and a divider 62 which divides a signal from the accumulator 61 with a number (n) of the detectors to get and average of the detector's signals. Moreover, the device 6 has subtracters 63-1 to 63-m to get a deviation value of each detector's signal. Here, (m) is a combination of arbitrary two, nC2. From the number n of the dectors. From each deviation signal e1 to em, a signal having the maximum deviation grade is selected by a selection circuit 65 after a value of each signal is made to be an absolute value by an absolute value circuit 64. After that, the selected signal is compared its deviation grade to a limit value by a comparator 66, and when the deviation grade does not exceed the limit, a position and shape controlling of a plasma, is executed using an average value of each detector signal as a feed back signal, for a plasma controlling device 7. When the deviation grade exceeds the limit value, the plasma stops gradually by a signal 67 which attenuates a value of a plasma electric current IP.
