DESCRIPTION:
This analyzer is identical to the Model 9254 except for the cesign of the source housing. The source hcusing of the 9254 is permanently attac1ec to the hand held probe, but the source housing of the Model 9264 is in the forn cf a cassette containing the source anc up to three filters, which can be rencved from the probe -
as a single unit. When me cassette is removed, the source is automatically put in a shielded condition ard will not become exposed unless the cassette is re-attached to the probe. This al'.cws for various sources to be used wit 5 the same analyzer unit so that tests may be made for several different elements using the same analyzer.
The hand held probe cor:ains the photomultiplier tube and als: may contain a 0.5 l
microcurie stabilizing scurce of Am-241.

X-Ray Fluorescence Analysis DESCRIPTION:
The 9200 Series X-Ray Fluorescence Analyzer is of the same basic design and has the same functior as its prototype, the Model 465. The or'ncioal difference lies in the electronics ard the design of the source housing. The analyzer consists of two units; the pr:ce which can be hand-held and contains a radioactive source, two filters, and a cetector; and the electronic unit, whicr. contains the power supply and output disolay.
I i
The instrumen is designed for " rapid, nondestructive, in situ elemental analysis in l
mining, geolocy, metallurgy, engineering and process control".
A radioisotope source is used to excite characteristic x-rays in the sample. The radiation from the sample is detected with a NaI(Tl) scintillation counter.
Coarse energy discrimination is afforded by the detector itself and a single channel pulse height L
Analyzer.
Incividual characteristic x-rays are isolated using balanced x-ray l
filters in the fom of thin foils placed over the detector window.
By suitable adjustment of thickness of the filters, x-ray transmissions can be made equal over a wide range of energies, except for the pass band between their two absorption edges, where the transmission will differ greatly.
In operation as a hand-held unit, the probe is pressed against the sample. One of the " feet" on the probe is automatically depressed and this causes the source shutter to open thereby exposing the source to the sample. As soon as the probe and sample are separated, the shutter springs back to cover the source. A second mode of operation is as a bench-mounted instrument, when small samples are placed over the aperture. In this mode, the shutter is actuated when the sample is covered by a cap which depresses the " feet".
All sources are weak gama or x-ray emitters and are encapsulated in a stainless steel cup such that radiation is emitted in only one direction.
For the sources with emission energy greater than 5 kev the window is covered with 0.3 m stainless steel and the source material is usually bound in the fonn of a ceramic enamel.
For the lower energy sources a 0.125 mm aluminum window is necessary. The radioactive L
material is either bonded or deposited as a ceramic layer. These capsules are more fragile than the stainless steel encapsulated sources.
Some models may contain a one-half microcurie americiuc-241 source in the probe head located in the light pipe between the photomultiplier tube and the NaI (Tl) crystal.
The 60 kev gacra rays from this source provide a means of stablizing the electronic gain for measurements where high sensitivity is required. The source is contained i

X-Ray Fluorescence Alloy Analysis DESCRIPTION:
The Texas Nuclear Model 9266 analyzer (also designated as "The Alloy Analyzer") is a fielc-portable instrument specifically designed for rapid, non-destructive, on-si e g
veri #ication of '" type" and " elemental composition" of many important engineering I
alloys.
The instrument is comprised of two interconnected parts:
a hand-held measurement probe which is placed against the metal to be analyzed, and a battery-powered, microprocessor-based electrcnic unit which provides several modes of measurement and presents the results visually, i
The measurement head weighs five pounds and is basically in the shape of a shallom (2.75" deep) cylinder (7" dia.) fitted with two handles: one of which is removable allowing attachment of the probe to a tripod or other clamping device. A souare block is located on the circumference between the handles and serves as a base fee standing the probe up-right for sample measurements.
The measurement aperture is located at the apex of a stainless steel, snout-like projection on the cylindrical surface diametrically opposite the base.
The sncut is sealed with a tough-to-puncture plastic window and contains the two primary, low energy radioisotope excitation sources.
Each source is totally enclosed within a tungsten-alloy shutter-collimator which reduces the external radiation dose rate to a negligible level. The shutters can only be actuated, one at a. time, in response to the programmed measurement routine. The status of each j
shutter; i.e., OPEN/ CLOSED, is clearly indicated on both the probe and the electronic unit. Several fail-safe provisions are also incorporated into the shutter control sequence.
j LABELING:
The probe is labeled with tags containing the conventional radiation symbol, the isotope, the amount of activity, assay date, model number and serial number of the unit and Caution-Radioactive Material - exposed when either source is in ON position
- DO NOT REMOVE THIS TAG. An additional tag is affixed to the probe head indicating the containment of a 0.5 microcurie Am-241 stabilizer source. The general license

CONDITIONS OF NORMAL USE:
The conditions of normal use would be any condition to which an individual may be subjected. These cotditions would include temperatures from -10 C to 60*C; vibration at 30 and 50 cycles; accelerator forces of 1 G atmospheric pressure.
Prototype units have been subjected to theme tests with satisfactory results.
The source housing and stutter design afford good protection of the sources against physical damage.
Additional safety is provided in the use of this instrument by a number of programmed test sequences. For example, the unit automatically senses the lines of communication betwee-tre main t! nit and the probe, the source shutter status, the power supply and metery condition of the ambient radiation background.
If any of the conditions are other than those programmed, the unit will not operate but will display an " Error" irdizating the problem. This would include the misalignment of a source collimator, arcient radiation increase in the detector due to contamination or conditions other :han those normal and proper to operation.
