“…The radius of the tube in which the bunch moves is 5 cm and it is for this a reason that maximal volume of the sample could be no more than a few cm 3 [14]. Because of the magnetic field inhomogeneity in such a large sample, its optimal volume should be limited to tens of mm 3 . It is not a serious limitation too, because we know of cases of research in high magnetic fields samples even of several µm 3 [15].…”

SummaryThis paper describes the estimation method of the spatial distribution of magnetic field induction and electric field intensity produced by a relativistic beam of charged particles. The described method is applied to estimation of this field distribution in surroundings of proton bunches which are accelerated inside the Large Hadron Collider (LHC). It is demonstrated that such bunches generate pulsed high magnetic fields with induction from a few dozen to a few hundred T within the space of a few cm. The fields are relevant to the successful application of research of materials properties in time intervals in the order of fs, which have not been available until now. We additionally present a design for a special chamber allowing easy introduction of samples into the accelerator, remote measurement and data acquisition.

“…Generation of these fields is most often achieved by use of coils supplied with high intensity electric current [1][2][3]. Unfortunately, this method has several deficiencies which limit the upper values of magnetic induction and time duration of these pulses.…”

“…Эти напряжения являются одним из основных факторов, препятствующих получению сильных магнитных полей. Для обеспечения прочности современных магнитов с рекордными полями в них используются катушки с равнонагруженными многослойными обмотками [1][2][3]. В таких магнитных системах внешний радиус связан с внутренним отношением exp(B 2 0 /2µ 0 σ 0 ), где σ 0 -предел прочности.…”

The mechanical stresses in the thin-walled quasi-force-free winding of the solenoid, which arise when a strong pulsed magnetic field is produced, can be significantly reduced if the winding is inserted into the area between two magnets creating crossed fields. It is shown that with a rational choice of the amplitude and shape of the external fields pulses the stresses can be reduced to values less than one tenth of the magnetic pressure of the generated field.

“…However, the field strength of pulsed magnets is severely constrained by the massive Lorentz force exerted on the conductors [11]. The magnetic stress generated in a 100 T pulsed magnet is 4 GPa, which exceeds the ultimate tensile stress (UTS) of any metal or metal alloy that are commercially available and approaches closely to the UTS of high strength fiber materials such as Carbon or Zylon [12], [13]. Any minor design error will result in the malfunction of the magnet [14], [15].…”

A modified mechanical model for the stress analysis of solenoid pulsed magnets is presented, which includes the influence of bending on the plane stress analysis. The bending effect in the axial direction is included by introducing the discrete axial strain with the assumption of the uniform distribution of the axial force load. The modified model improves the accuracy remarkably compared to the classical Generalized Plane Strain (GPS) analysis. The results are verified with the FEA software. The algorithm of identifying the optimum positions of the separations between windings is also proposed. This model achieves both high efficiency and high precision, which are of great significance to optimize high field solenoid pulsed magnets and explore the existing potential for higher magnetic fields. INDEX TERMS Bending, high magnetic field, pulsed magnet, separation, stress analysis.
