Description
(54) УСТРОЙСТВО ДЛЯ КОРРЕКЦИИ НЕОДНОРОДНОСТИ МАГНИТНОГО ПОЛЯ ЭЛЕКТРОМАГНИТА(54) DEVICE FOR CORRECTING THE INHOMOGENICITY OF THE MAGNETIC FIELD OF ELECTROMAGNET
из двух одинаковых тонких попос фольги, расположенных в плоскости, перпендикул рной оси Ъ , на рассто нии + Ъ от начала координат , совпадающем с центром помещаемого в зазоре электромагнита образца. Средние лиНИИ полос лежат в плоскости X , Длина полос определ етс согласно соотношению е :.15 Zp , а ширина VT2 ZQ .of two identical thin cross-sections of the foil, located in a plane perpendicular to the b axis, at a distance of + b from the origin, which coincides with the center of the sample electromagnet placed in the gap. The middle lines of the bands lie in the X plane. The length of the bands is determined according to the ratio e: .15 Zp, and the width VT2 ZQ.
Через полосы 1 пропускают электрический ток с помощью проводников 2, соедин ющих обе полосы так, что токи в них направлены в одну сторону. Проводники располагают по кра м электромагнита с условием, чтобы они не вли ли на магнитное поле в образце.An electric current is passed through the strips 1 by means of the conductors 2 connecting the two strips so that the currents in them are directed to one side. The conductors are placed around the edges of the electromagnet with the condition that they do not affect the magnetic field in the sample.
Контуры,компенсирующие составл ющую, измен ющуюс по закону X, выполнены аналогично изображенным на фиг, 1, но повернуты на 90 вокруг оси ЪThe contours that compensate for the component, varying according to the law X, are made similarly to those shown in Fig. 1, but rotated by 90 around the axis b
Контуры, компенсирующие составл ющую пол , измен ющуюс по закону Z У (фиг. 2), имеют вид полос, соединенных так, что направление тока в них противоположно, а юс ширина f 2 S, .The contours that compensate for the component of the field, varying according to the law Z Y (Fig. 2), have the form of strips connected in such a way that the direction of the current in them is opposite, and here the width is f 2 S,.
Контуры, компенсирующие составл ющую, измен ющуюс по закону 2. X, аналогичны, но повернуты на 90 вокруг оси Ъ ,The contours that compensate for the component varying according to law 2. X are similar, but rotated by 90 about the b axis,
Использование описанного устройства в электромагните радиоспектрометра позвол ет получить высокое разрещение без боковых полос, обусловленных вращением, при вьшолнении полюсов из серийно выпускаемых материалов и с меньшей, чем в прототипе, потребл емой электромагнитом мощностью.The use of the described device in an electromagnet of a radio spectrometer allows to obtain a high resolution without sidebands due to rotation, when performing poles from commercially available materials and with less power than an electromagnet consumed by the electromagnet.
