Ad-Vance Magnetics, Inc.

United States

Selecting a magnetic shield for photomultiplier tubes is simplified because Ad-Vance Magnetics has fabricated magnetic shields for most PM tubes sizes and are already tooled up for most of the PM tube sizes. It is only necessary to inform us of the PM tube manufacture's name associated on our PMT Shield list (located below) and the tubes number to obtain the correct magnetic shield shape. If your tube is not listed on our list please let us know the sizes you wish for the magnetic shield to be and we can custom fabricate this magnetic shield for you and most times can still use current tooling. PMT Magnetic shields can be supplied with or without a flat black enamel coating on both the inside and outside surfaces.

Magnetic shielding is needed to protect critical electronic components from unwanted interference. A magnetic shield will divert the magnetic field around it and various different directions. This is similar to how a rock diverts water around it in a river stream. The most common magnetic shielding materials are Ad-Mu-80 and Ad-Mu-48, which high permeability and medium permeability magnetic shielding materials.

Custom fabricated magnetic shields can be made to protect any kind of equipment in almost any configuration. Magnetic shield shapes can range from a simple box, conical or cylindrical configurations to more complex shapes and sometimes conform to inside or on top of another unit. In complex situations magnetic shields are fabricated to fit exactly and can consist of many unusual configurations. With our in house fabrication capabilities we can stamp, spin, bend, laser cut, photo etch, weld, spot weld and assemble magnetic shields your exact specification.
