International Classification:

H01J 3/00
G01N 27/62

US Classification:

2502521, 250397, 25049221, 324 713

Abstract:

An ion beam angle calibration and emittance measurement system, comprising a plate comprising an elongated slit therein, wherein the elongated slit positioned at a rotation center of the plate and configured to allow a first beam portion to pass therethrough. A beam current detector located downstream of the plate, wherein the beam current detector comprises a slit therein configured to permit a second beam portion of the first beam portion to pass therethrough, wherein the beam current detector is configured to measure a first beam current associated with the first beam portion. A beam angle detector is located downstream of the beam current detector and configured to detect a second beam current associated with the second beam portion. The plate, the current beam detector and the beam angle detector are configured to collectively rotate about the rotation center of the plate.

Assignee:

Neutron Therapeutics, Inc. - Danvers MA

International Classification:

H05H 6/00
G21G 4/02

Abstract:

Design and making methods of a neutrons generating target are described. In some embodiments, a surface of a target substrate can be modified to form one or more surface features. In some embodiments, a neutron source layer can be disposed on the surface of the target substrate. In some embodiments, the neutron source layer and the target substrate can be heated to an elevated temperature to form a bond between the two. In some embodiments, the surface modification of the target substrate can reduce blistering and material exfoliation in the target. The target can be used in boron neutron capture therapy.
