摘要： A magnet device includes two sets of static magnetic field generation sources spaced from each other in the vertical direction such that the uniform magnetic field region (patient space) is between then. Each set has concentric current carrying coils to generate a uniform magnetic field in a first direction (the vertical direction). Several such coils are used in each set, disposed such that when a first axis which is parallel to the first (vertical) direction and passes substantially through the centers of the current carrying coils crosses, at a first point, a second axis which is orthogonal to the first axis and is at substantially equal distance from the respective static magnetic field generation sources, the current carrying coils are disposed in such a manner that when geometrical centers of cross sections of the current carrying coils are projected on a first straight line that is in a first plane containing the first axis, the second axis and the first point and passing through the first point, the directions of the currents of the carrying coils at the respective corresponding projections align alternatively in positive and negative directions on the first straight line.

摘要： A charged particle beam drawing apparatus and a pattern forming method capable of drawing fine patterns while minimizing the proximity effect, thus overcoming the drawbacks of the conventional exposure area density correcting method and supplementary exposure method. The inventive method comprises the steps of performing supplementary exposure by irradiating a drawing area on a specimen with a charged particle beam, and performing main exposure by irradiating with the charged particle beam a region made up of the drawing pattern inside the drawing area on the specimen. The supplementary exposure step includes the steps of: dividing the drawing area into a plurality of smaller regions of an equal area each while calculating an area value of the drawing pattern in each smaller region; correcting the area value of each smaller region by use of a weighted sum of the area values calculated for proximate smaller regions surrounding the smaller region in question; generating supplementary exposure geometries for the drawing area; and computing doses of exposure for the generated supplementary exposure geometries by referring to the corrected area values.

摘要： A superconducting magnet apparatus. By forming one or more holes in each of platelike ferromagnetic substances forming a magnetic shield for focusing the magnetic flux generated by superconducting coils, the flow of lines of magnetic flux is adjusted. Thereby, a static magnetic field in a measurement space is corrected. By disposing coupling tubes for supporting two cooling vessels housing superconducting coils on the rear side with respect to a central axis (Z axis) of the measurement space of the vertical direction, access to the subject is facilitated. In addition, the magnetic shield has an opening portion wider than the superconducting magnet on its side face. After the magnetic shield has been assembled, the superconducting magnet can be inserted from the opening portion.

摘要： The present invention relates to techniques for enlarging an opening, which accommodates a subject, in a superconducting magnet apparatus for use in MRI system, so as to prevent the subject from feeling claustrophobic, and for realizing low magnetic field leakage therefrom, and for reducing the weight thereof, and for realizing a large high magnetic field strength uniform magnetic field region. Static magnetic field generating sources of the superconducting magnet apparatus are constituted by two sets of superconducting coils, the respective sets of which are placed in such a manner as to face each other across a uniform magnetic field generating region. Each of the sets of superconducting coils consists of a main coil for feeding electric current in a specific direction, a bucking coil for feeding electric current in a direction opposite to the direction of the electric current flow passing through the main coil, and a coil for correcting magnetic homogeneity. The diameter of the aforementioned main coil is set as being nearly equal to that of the aforesaid bucking coil. Further, the diameter of the coil for correcting the magnetic homogeneity is set as being less than that of the main coil. Moreover, an amount of electric current flowing through the coil for correcting the magnetic homogeneity is set as being less than that of electric current passing through the main coil. Furthermore, the distance between the two main coils facing each other is set as being shorter than that between the two bucking coils.
