General Purpose Computers
In room 3011, we have four general-purpose computers. These can be used
for plotting and analyzing your data, writing and printing your lab reports,
searching the web for information, sending email to the professor, etc.
Two of the computers are Macintosh G3's and two are Dell Dimensions running
Windows NT. All of these computers are connected to the building network.
Each computer should have a sign on the wall above it, listing the software
available on it. All the computers have floppy, zip, and CD drives. You
can save your work on removable media, but I would strongly suggest that
you also save it on the hard drive. In the past, we have had disasters
in which someone's floppy with their data would suddenly become unreadable.
If you have your own computer, feel free to use it.
If you have never used a Mac before, see the attached sheet
"How to Use a Macintosh" for easy instructions. Our Macs don't have
separate accounts for different users. This has three consequences:
- We are not allowed to ftp from these machines, since
there is no way to authenticate a user.
- To keep the hard drive organized, each student should create
their own folder inside the folder called "Students put your files here".
Use this folder to save any files you create during the quarter.
Please do not put them in the Kaleidagraph folder, the Excel folder, etc.
- If you want to do web searches, you should use the Profile
Manager in Netscape Communicator to create your own profile. That way,
each student can maintain their own bookmark file. There is a profile
called "616 Students" which you can use if you wish, but it doesn't have
many useful bookmarks and so there is not any advantage to it.
The Macs are set to print to the Laser Writer in room 3011.
You can also select from a list of other printers in the print dialog
box for whatever application you are using. Or you can print by dragging
a document to one of the printer icons on the desktop.
Remember that these Macs can read a floppy that is PC-formatted,
but not vice-versa.
The Windows NT computers:
Use your regular physics department NT account to log on to these.
If you don't have an account, see J.D. Wear or one of the other members
of the computer support group in room 2180. These computers are fairly
new and don't have much software installed yet. If you have suggestions
for software, please tell Margie.
The Dells are connected to the Apple LaserWriter in 3011 and the
HP Laser Jet in room 3012. You can set either of these to be your
default printer, using "Settings" in the Start Menu.
We have some older computers that are dedicated to specific experiments
for data collection. Some of these also have software such as Word and
Kaleidagraph, so you can use the same computer to work on your lab report.
We have three Macintoshes, used for the Compton Effect, Muon Lifetime,
and Scintillation Spectrometer experiments. These contain National
Instrument acquisition cards and run LabView to collect data,
operating similarly to the computers in Physics 416.
They all print to the Laser Writer in 3018.
The Compton Effect computer is connected to the building network, so you can
transfer your data to a different (newer, faster) Macintosh for analysis if
you wish (see "How to Use a
This computer can also be used to download data from the Canberra MCA
which is used for other nuclear physics experiments. The other two
computers in 3018 are only connected to the printer. If you want to
transfer your data to another computer, you will have to put it on a floppy.
The Kater Pendulum experiment has a Mac IIsi for data collection.
It is hooked up to the building network, so you can print to any printer
or transfer your data.
The X-Ray experiment has an old PC that runs a data collection
program in DOS mode. The AFM uses a special purpose HP computer.
Both of these can print to the Laser Jet in 3018, using an A/B switch.
Neither is networked. For both of these experiments, I suggest that when
you have data to save that you copy it to a floppy and then copy
the data onto another, more reliable computer as soon as possible.
