Even when current is supplied from the power source to the trajectory correcting electromagnet 3 and the converging or diverging electromagnet 4 which are other electromagnets other than the deflection electromagnet 2, only operating parameters such as applied current are different.
- the configuration for supplying current from an electromagnet power source to each of a plurality of electromagnets via a cable is the same. The applied current and the like will be described in detail later.
- FIG. 3 is a conceptual explanatory diagram of the case where the deflecting electromagnet 2 which is a typical electromagnet as the electromagnet of the synchrotron 1 is taken and this electromagnet and the connection plate group 20 are connected.

- the representative size) is larger than the size of the connection plate, and as a result, in terms of the site area ratio required for cable installation, it is two to three times that when the connection plate is used. In other words, if a connection plate is used, the site area necessary for installing the connection plate (area required for installing only the connection plate) is less than half that of using a conventional cable. It turns out that.

- the y direction is the radial direction (hereinafter the same) of the annular installation positions of the various electromagnets constituting the synchrotron 1, and the upper side in FIG.
- a connection plate connected by such a connection portion is configured to be connected in series between two adjacent deflection electromagnets with these connection portions as a boundary (two adjacent deflection electromagnets 2c, 2d). 2 are representatively shown as reference numerals (1), (2) and (3) in FIG. 2.

- the bent connection portion 22 that is bent in an S shape is provided in a part of the connection plate, thereby strengthening the connection state in which the divided connection plates are connected in series and working. There is an aim to make it easier.
- the reason why the bent connecting portion 22 that is the inner connecting portion of the connecting portions of the two connecting plates is bent is that the fastening operation by the screw fastening portion 27 even when the two connecting plates are close to each other. This is so that the above can be easily performed.
- FIG. 5 is a view showing a CC cross section of FIG. Connection plates 21a and 21c, which are two sets of adjacent sets having a thickness h 1 and a width h 2 (in each of the two sets, the above-mentioned one piece (each (1), (2), (3) in FIG. 2) corresponding) corresponding to the connection plate) is intermediate fixing plate (material: a glass epoxy laminated board) 24, an insulating space formed with an insulating material having a thickness of h 3 (material: at a glass epoxy laminated board) 28 It is fixed.
- the z direction is the width direction of the connecting plate and corresponds to the height direction (the same applies to the following figures).
- the thickness h 1 of the connecting plate, the thickness h 3 of the insulating plate, etc. are negligible values of 0.01 or less compared to the outer peripheral size of the synchrotron 1, and in plan view, the connecting plate It can be said that the installation position of is on the substantially outer periphery of the synchrotron 1. Therefore, when installing a cable whose outer diameter size is more than twice the size of the connection plate (particularly the size in the thickness direction (2h 1 + h 3 )), particularly, the cable is connected to the outside of each electromagnet of the synchrotron 1. If it is necessary to install on the ground, the required installation area is further increased. In other words, when the connection plate is used, the necessary site area can be reduced by the size of the cable as compared with the case where the cable is used.
- connection plates are usually installed at a height h 4 from the installation reference plane, a lower space S of the connection plate (or intermediate fixing plate) is formed, so that there are restrictions on the site area, etc.
- the lower space S can be effectively used as compared with the case where a cable is used (for example, a part of the space can be used as an installation space for cooling equipment piping).
- a cable since it is usually installed directly on an installation reference plane (for example, the ground), there is no lower space S.
- FIG. 6 is a view showing the direction of arrow D in FIG.
- the connection plate 21 having a width h 2 (specifically, the two connection plates 21a and 21b are connected in series using the screw fastening portion 27) is a height (installation reference height; the same applies hereinafter) from the installation reference plane. It is fixed at the position h 4 by the intermediate fixing plate 24 and is clamped by the clamping plate 25 and installed.
- Reference numerals 29a, 29b, and 29c are fastening bolts.
- FIG. 7 is a partially enlarged view of the deflecting electromagnet connecting portion 23 of FIG. 2, schematically showing the connection state of the connection plate 21 and the connecting end 30 of the deflecting electromagnet in order to supply current to the deflecting electromagnet.
- the electromagnet such as the deflection electromagnet 2 is installed at a higher position (> h 2 + h 4 ) than the position of the height h 4 from the installation reference plane, which is equal to or greater than the distance h 2 of the connection plate 21.
- the connection plate has an L-shape at this portion and is bent upward (z direction in the drawing) (see connection plates 21d and 21e).
- FIG. 8 is a partially enlarged view of the joint connection portion and shows a connection portion with the cable 8.
- the cable 8 is divided into two pieces from the electromagnet power source 7 (see 8a, 8b and 8c, 8d in the figure), and each cable end is fixed to the intermediate fixing plate 24 via the crimp terminal 31. It is connected to the two connection plates 21f and 21g (see the description of FIG. 3). Also in this case, the mounting position of the intermediate fixing plate 24 of the connection plate from the installation reference plane (target installation height) is h 4, it is similar to that of FIGS. 5-7.
- connection plate group 20 is more advantageous than the method using the conventional cable for installing the entire equipment of the synchrotron 1 with a small installation area.
- the above-described cooling facility is required in addition to the connection plate group 20 which is a current supply facility, and therefore a site for the cooling facility is further required. Even in such a case, when the use of the lower space S is considered, it can be seen that the method using the connection plate group 20 is more advantageous than the cable method.
- FIG. 1 is a schematic diagram showing an example of an operation pattern of a current passed through an electromagnet used in a synchrotron such as a deflection electromagnet. Since a plurality of deflecting electromagnets are installed as shown in FIG. 2, in order to accelerate protons and the like, it is necessary to operate them synchronously. Therefore, the current pattern applied to these electromagnets is patterned as a trapezoidal current as shown in FIG.
- the vertical axis represents the current value to be applied
- the horizontal axis represents the elapsed time.
- the amount of change per unit time in the current value of the portion indicated by G is the same.
- the portions indicated by symbols F1 and F2 are portions where the current value is constant, the maximum current value A 1 in the F1 portion, and the minimum current value in the F2 portion. It is patterned to a 2.
- the reason why the portion F2 is provided is that the current value is abruptly changed from the portion indicated by the symbol G (the portion having a negative inclination) to the portion indicated by the direct symbol E (the portion having a positive inclination). This is because it is difficult in practice, and it is necessary to provide a flat portion having no current change such as the F2 portion.
- the bending magnet A 1 is the current value of the order of 1000A
- a 2 is the current value of 1 in the order of 10 minutes is usually set.
- the maximum current value A 1 becomes one order smaller
- the pattern of applied current depending on the type of the electromagnet such even minimum current value A 2 is set to 1/4 or less of the value It is different.
- the size of the connecting plate to be used that is, h1 and h2 is determined using the allowable current value per unit cross-sectional area determined corresponding to these applied currents as one reference. That is, it is necessary to determine the size of the connection plates h1 and h2 so that the current is less than the allowable current value.
- the embodiment can be appropriately modified and omitted within the scope of the invention.
- the case where the bending connection portion is located on the inner peripheral side of the synchrotron has been described as an example, but not limited to this case, even when the bending connection portion is located on the outer peripheral side of the synchrotron, The same effect is produced.
