An active charge –exchange q measurements in ITER based upon the diagnostic hydrogen beam
The active charge exchange technique based upon Secondary Charge Exchange effect (SCX) is proposed for safety factor measurements in ITER. The performed numerical modeling shows that measurements of the magnetic pitch angle are possible up to the plasma center with radial resolution of 5 cm and in...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The active charge exchange technique based upon Secondary Charge Exchange effect (SCX) is proposed for
safety factor measurements in ITER. The performed numerical modeling shows that measurements of the magnetic
pitch angle are possible up to the plasma center with radial resolution of 5 cm and integration time of about
10 ms. A systematic inaccuracy amounts several milliradians. An important advantage of SCX technique is the
possibility of direct pitch angle measurements. |
