User Authorization Forms

Discuss your proposed experiments with the EMAL Staff, they will determine if your research can actually be performed with the equipment available in EMAL and will identify the appropriate instrument for you to use. The EMAL Staff will then request that the user complete an EMAL Authorization Form.

There are in fact, two different EMAL Authorization forms, which one you must use is dictated by your institutinal affiliation:

  1. Authorization form for UM Users.

    This form must be filled out by the person who is responsible for the funding of the research (typically a faculty member) and it lists the contact address, phone number and email address of that person and also the same information for the user. In addition a University account number must be supplied for recharging the instrument use and supplies. The purpose of this form is three-fold:

    • Firstly, since the users of the laboratory are typically graduate students, this form notfies the student's advisor that the student is using EMAL, and spending that advisors research budget.
    • Second, the EMAL staff know that the faculty advisor has sanctioned the work in EMAL and have a valid account to which the useage may be recharged.
    • Finally the user must indicate on the form that he/she have read the radiation safety information that is relavent to the particular instrument that they are going to use.
  2. Authorization form for Non-UM Users.

    Users from outside the University of Michigan are requested to provide the same information, however, they are also asked to furnish a purchase order to which the usage can be charged. Purchase orders should be made out to "The University of Michigan Electron Microbeam Analysis Laboratory" and mailed or faxed to the laboratory. The User Fees vary depending on the type of user and the time of day that the equipment is used.
