“…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]. The research of small-sized samples is consistent with a current need of miniaturization in electronics and nanotechnology.…”

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.

“…Moreover the possibility of latching leads to the fact that only a pulse of force is necessary to switch from one stable to another stable position. For such systems a pulse of current is sufficient and for evident thermal reasons, the possible current density achievable for such a pulse current, and so the forces, can be much higher than for a DC system [31].…”

Electromagnetic remote control and downscaling advantages and examples for MOEMS

Electromagnetic actuation is applied to MOEMS for industrial applications requiring large and long-range forces. Advantages and drawbacks are outlined while down scaling laws are discussed. Technological improvements and new available materials bring to much smaller dimensions, the limit between Electromagnetism and Electrostatics. Remote control and bi-stability are unique characteristics of electromagnetic actuation. The importance of remote control is stressed so as to allow easy tests and optimisation with no technological compatibility problem. These advantages are illustrated on three different electromagnetic MOEMS, developed in LIMMS, a Franco-Japanese research Laboratory based in Tokyo. The first is a resonant 1D magnetic scanner, the second is a magnetic bi-stable matrix array of optical micro-switches and the last is a remarkable application of the properties of thick Magnetostrictive thin layers to a 2D scanner.

“…The coil dimensions are of order of 100 m, and strong pulsed fields can be obtained with a total energy of less than 1 J. In fact, Mackay et al 5 successfully generated 50 T in such a microcoil, and suggested the use in magneto-optic experiments such as Faraday rotation.…”
