SPECIFICATIONS

For guidance in this project CERN has specified the following specifications:

The inclinometer must be insensitive to the magnetic field at 9 T
The inclinometer must have an accuracy of 0.1 mrad
The diameter of the inclinometer must be 32 mm or less
The length of the inclinometer must be 30 mm or less
The weight of the inclinometer must be 100 g or less

The first three specifications are very rigid. These must be met in order for the project to be a success. The last two specifications are modifiable items. This means that the longer lengths and larger weights can be accommodated as long as the difference is not greater than a factor of two.

From the customer specifications, it has been determined that the best choice in materials is that of anti-ferromagnetic materials, or some special alloy. Anti-ferromagnetic materials have a complete magnetic moment cancellation, such that the material possesses no net magnetic moment.

It should also be noted that a prototype representing the final product should be built. However, the prototype must again satisfy the first two specifications mentioned above. A proof of principle will be used in order to show that a prototype built to the actual specifications would still display the same characteristics of the model.
