    摘要： An accelerator (30, 40, 50) includes: a plurality of acceleration cavities (31, 41, 51) having one or two acceleration gaps; and a plurality of first control means (33, 43, 53) provided with respect to each of the plurality of acceleration cavities, each of the plurality of first control means independently generating an oscillating electric field and controlling a motion of an ion beam inside a corresponding acceleration cavity. In addition, M-number of multipole magnets (32, 42, 52) which generate a magnetic field and which control a motion of an ion beam may be provided downstream to N-number of acceleration cavities. The first control means independently controls acceleration voltage and a phase thereof and supplies radiofrequency power. Accordingly, particularly in a front stage of acceleration, a DC beam from an ion generation source can be adiabatically captured.

    摘要： A time-of-flight (TOF) measurement system for measuring energy of a pulsed hadron beam, wherein each pulse of the beam is structured into a series of bunches (B) of charged particles, said bunches being repeated according to a repetition rate of the order of magnitude of radiofrequency. The system comprises
    a first detector (1), a second detector (2) and a third detector (3) arranged along a beam path (10), each of the detectors being configured to detect the passage of a bunch (B) of charged particles and provide an output signal (v PP,1 , v PP,2 , v PP,3 ) dependent on phase of the detected bunch (B), wherein the second detector (2) is spaced apart from the first detector (1) by a first distance (L 12 ) and wherein the third detector (3) is spaced apart from the second detector (2) by a second distance (L 23 ), wherein the first distance is set out in such a way as that time of flight (t 12 ) of the bunch (B) from the first detector (1) to the second detector (2) is approximately equal to, or lower than a repetition period (T RFQ ) of the bunches (B), and wherein the second distance is set out in such a way as that time of flight (T 23 ) of the bunch (B) from the second detector (2) to the third detector (3) is greater than a multiple of the repetition period (T RFQ ) of the bunches (B), and
    a processing unit (7) configured to
    a) calculate phase shifts (Δ ϕ12 , Δ ϕ13 , Δ ϕ23 ) between the output signals (v PP,1 , v PP,2 , v PP,3 ) of the detectors (1, 2, 3), and
    b) calculate energy (E) of the pulse based on the calculated phase shifts.

    摘要： The objective of the present invention is to manufacture an acceleration device and a mass analysis device inexpensively and with a compact size, enabling them to be used by any person. The mass analysis device (300) is configured from a plurality of substrates, including a first main substrate (301), a first upper substrate (302) adhered to the upper surface of the first main substrate (301), and a first lower substrate (303) adhered to the lower surface of the first main substrate (301). A mass analysis chamber (308) is a passage formed in the first main substrate (301) and running from the upper surface of the first main substrate (301) to the lower surface of the first main substrate (301), and enclosed in the direction perpendicular to the substrate surfaces (the Z direction) by the upper substrate (302) and the lower substrate (303), enclosed on both sides in the direction (the direction X) which is orthogonal to the Z direction and is the direction of advance of charged particles (318) by first main substrate side plates (301-4, 301-5), and enclosed on both side surfaces in the direction (the Y direction) orthogonal to the Z direction and the X direction by the first main substrate (301). A center hole (310-4) is opened in the first main substrate side plate (301-4) to which the charged particles (318) are incident, and the charged particles (318) enter the mass analysis chamber (308) from the center hole (310-4) formed in the first main substrate side plate (301-4).

    摘要： This superconducting accelerator comprises: an accelerating cavity that forms a space in which a charged particle beam is accelerated in a superconducting state; and a refrigerant vessel (11) that is disposed on the outer peripheral side of the acceleration cavity and in which a refrigerant for cooling the accelerating cavity is filled in a gap to the accelerating cavity. The superconducting accelerator further comprises a pair of pressing members (21) that are provided on the outer peripheral section of the refrigerant vessel (11) and are respectively provided to both end sections of the charged particle beam in the beam axis direction in the acceleration cavity or to both end sections in a direction orthogonal to the beam axis direction. The superconducting accelerator further comprises: a wire (22) that is continuously provided on the outer peripheral section of the refrigerant vessel (11) and that generates tension in a direction that brings the pair of pressing members (21) closer to each other; and a tension adjustment part (25) that adjusts the tension generated by the wire (22).
