*Remember, if you are going to use ANY laboratory at the University of Michigan, you should take the required safety training organized by OSEH first!
|What is EMAL?|| The University of Michigan Electron Microbeam Analysis Laboratory or
EMAL is a university-wide USER facility for the structural and chemical
characterization of materials at nanometer length scales.
The laboratory was originally established in 1978 with the goals of providing and maintaining state-of-the-art equipment for use by the university research community. The laboratory was divided into two when the Department of Materials Science & Engineering moved to its current North Campus location.
|Where is EMAL?|| The addresses of the two locations are as follows:
Maps are also available to locate the two labs.
|What is available in EMAL?||Information on the instruments in EMAL is available on the instruments web pages. If, however, you are looking for a description of the current instruments in the facility that you wish to include in a proposal or to send to prospective new faculty, then please see the EMAL description documents that are available in Microsoft Word format or PDF format. If you have questions about this document, please contact John Mansfield .|
|I need to use EMAL, what do I do?||
|How do I know which Instrument use?|| If you email John Mansfield, Kai Sun or Carl Henderson with the answers to the first two questions above, then we can help you choose the
You can also peruse the instrument information on this website.
|How much will it cost?|| All of the instruments in EMAL are charged at the same rate.
How much your particular research problem will cost depends on your experience and on what
you are trying to do.
|I am not from the U of Michigan. Can I still use EMAL?|| Yes. We have several users from other universities and local industry. Call or send email to John Mansfield (734) 936-3352, Kai Sun (734) 936-3353, Haiping Sun (734) 936-3338 or Carl Henderson (734) 615-6657.
You will need to set up a PO payable to "The University of Michigan", or have a credit card to
charge your microscopy time to.
|My advisor wants me to "get trained" but I don't have samples yet.|| When you have your research samples ready to be examined, the staff will arrange a time to train you.
Users are trained on the EMAL instruments while examining their own research samples.
During the training session you will learn some operating tips specific to your samples and will usually
get some initial results for your research project.
|But can't I get trained on practice samples now and come back when I have my own samples?|| The Staff of EMAL have found that if they train users who have no
samples of their own, then two things typically happen:
EMAL has limited staff and many users (see these statistics for further information) and repeat training sessions wastes valuable time.
|It will take me too long to learn. Can't you just do it for me?|| In a word, no. EMAL has limited staff and many users (see these statistics for further information) and there
are not enough of us to perform service work. Much of the research that is carried out in EMAL
could not be done on a service basis anyway, as the problems to be solved are too complex to
be answered on the basis of a few hours of TEM time and a handful of images.
|How much will it cost to "get trained"?|| Learning how to use the basic functions of any of the instruments in EMAL may be quite straightforward.
While users are being trained the rates are those applicable to normal use by that class of user (university, external university or industry), plus the standard operator assistance charge for that class of user.
How much it costs for you to become an expert user will depend on
exactly what you are trying to do. It maybe that you have to collaborate with members of the EMAL staff to get your initial results and/or complete your project.
|Does the EMAL staff do collaborative projects?|| Yes, indeed EMAL staff can become involved in research projects and prospective collaborators should contact John Mansfield, Kai Sun, Haiping Sun or Carl Henderson for further details. Note that again there is a limit to these collaborations because there are only 2.2
full-time staff in the NC EMAL and 2 full-time staff in CC EMAL.
|I see that I have been charged for operator assistance, that means that I don't have to put any of the EMAL staff as co-authors on any of my papers, right?|| The operator assistance charge is $10 per hour and is therefore really
only a token charge, but where the EMAL staff have simply shown users
how to align the instruments and determine which buttons to press, then
it is assumed that there is no serious contribution to the research
project and co-authorship is not expected. However, if any of the EMAL
staff have helped design the series of experiments, helped prepare the
samples, performed a significant amount of the microscopy and have had
a role in the interpretation of the data then it is only common
courtesy to add their name(s) as co-authors on any subsequent publications.
|Do I have to acknowledge EMAL in my publications?|| Yes, this is extremely important. Publications citing EMAL use are
essential when a proposal is being prepared for a replacement
instrument, when the current equipment begins to wear out or become
obsolete. A reprint of any publication that contains data recorded in
EMAL should be supplied to John Mansfield, Kai Sun or Carl Henderson.
We would like a copy of all Ph.D and MS theses and will pay for the
copy if necessary.
|I think I saw some graduate students from another research group training new users, can I do that?||Maybe. There are
a number of groups who have a long and continuing relationship with
EMAL and have a number of senior graduate students and post-docs who
have considerable experience on the EMAL instruments. When they have
new users in their groups the more experienced users will often work
with the new users to get them started on their projects and familiarize
them with the instruments. The senior user must be in the instrument
room at all times during any such introduction. The EMAL staff only
permit this when they know that the senior student users are very experienced
and know exactly how the staff would like to see the new users trained.
New users must all be reviewed by EMAL staff prior to using the instruments
on their own.
|Can I book as much time as I want on the microscopes?||In a word: NO
Users should remember that the North Campus Instruments are very popular and have several hundred registered users. For this reason regular daytime access is limited to ONE 4-hour slot per user per week. So, when booking in advance for any particular calendar week you may only book one slot in the 8am to 5pm time frame. If, at the beginning of any particular week, there are day time slots available, you may then book additional slots. Users booking multiple slots in advance may have their access to the North Campus EMAL restricted.
