The design and capability test of miniature Penning ion source

A miniature Penning ion source is designed which anode canister is 10 millimeters; it can meet the need of the small well logging neutron tube that requires ion source miniaturization, high neutron yield and good stabilization. The structure and electromagnetism field is designed reasonably; the ion source has good current stabilization, high neutron yield and good performance. The miniature Penning ion source can satisfy the request of the small well logging neutron tube.
