**I. PROJECT DESCRIPTION**

> A. Project description and approach:

The aim of the first phase of this project is to make a fast detector
capable of detecting a beam of particles with an ultra-fast rise time,
in an easy and a non-destructive way. A laser polarimeter is utilized
which senses the electric field created by a charged beam when passing
by an electro-optic crystal. By using the Kerr effect we observe the
ellipticity induced change in the laser amplitude escaping the analyzer
by a fast photo-detector. For most part the laser light will be enclosed
in the fiber and the crystal, being exposed only immediately after the
laser and before the photo-detector. The trained people will use the
room for tests, and storage of equipment relevant to the project. Low
voltage (less than 10V) and low current fast pulsers may be used for
calibration. All the optical surfaces will be regularly cleaned with
ethyl alcohol or acetone.

> B. Describe the **Apparatus** and the **operating conditions and
> maintenance procedures** that will be used**.** List Special Equipment
> (X-ray generators, lasers, radioactive sources, etc.) that will be
> used during the project:

The apparatus used are the laser, a low voltage (less than 10V) pulser,
voltmeters, photo-detectors, oscilloscopes and other electronic devices.

The setup consists of a laser, two polarizers to polarize and analyze
the light, the crystal which is the sensing device and fibers to bring
the laser light to the crystal and take it out for analysis. After the
analyzer there is a photo-detector and then an oscilloscope.

The duration of the tests at times is expected to require the laser to
be on without the users being in the room.

The laser is an OMNICHROME(532-50GS) Ar ion laser capable of delivering
a maximum of 50mW in the 514.5nm wavelength. It does not require gas
bottles in the room. The other laser is a solid state IR laser with a
maximum of 200mW in the 1310nm wavelength.

The maintenance requirements only involve the cleaning of the optical
surfaces with ethyl alcohol or acetone and occasional laser tuning.

> C. Describe the expected **duration of the experiment** and the
> experiment **termination or decommissioning** procedures, including
> disposal of hazardous materials, that will be necessary to return the
> laboratory to a condition suitable for other projects:

This project received an LDRD funding for two years starting Fall 1998.
The de-commissioning procedures include the dismantling of the setup and
storage of the laser, and other optical equipment. There are no special
needs during this stage.

**II. CHEMICALS INVOLVED IN THE PROJECT** *MSDSs for commercial products
can be obtained from the vendor, or through the BNL CMS Database
http://www.sep.bnl.gov/cms/.*

> A. List **all** chemicals (including solvents, resins, epoxies, etc.)
> and estimate the quantities of each that will be used during the year.

Ethyl Alcohol 1 liter/year. Acetone 1 liter/year.

> B. List any chemicals that require special precautions.

None.

**III. ENVIRONMENT** Review the project from the perspective of the
environment, including air emissions, waste water discharge, hazardous
and solid waste, etc. Include radioactive and non-radioactive waste
streams.

A.  **[Waste Disposal]{.underline}** Identify the **quantities** and
    disposal **methods** of the products and waste materials involved in
    the project.

There is going to be only the regular wastes in the approved fashion.

B.  **[Waste Minimization Plan]{.underline}** Waste minimization
    measures must be part of the review.

Only minimal amounts of waste are generated by this project. New
materials are evaluated for their impact on the waste stream. Non
hazardous alternatives are used wherever possible.

C.  [Environmental Threshold/Priority Determination]{.underline} Fill in
    the following tables. "Per Run" means each time the experiment is
    run. Do not include radioactive \"calibration\" sources.
