So you want to build an experiment?A Technician’s Perspective
Syllac Torroidal Pinch Machine - Operations
Antares CO2 Laser – Assembly and installation of optical mounts and performed optical alignment of laser system from the front end to the target chamber.
Lujan Neutron Scattering center - Built several neutron spectrometers and diffractometers.
Nevada Test Site – Built and fielded x ray line of sight diagnostics.
Pegasus Pulsed Power – Operations
Colt Pulsed Power – Helped build and operate.
Trident – Operations, Modified North Target Chamber. Currently involved in Short Pulse Compressor Chamber development.
WHAT DO YOU WANT? A STARSHIP? (Dreamy, but not likely)
WHAT DO YOU NEED?An environment / tool for your experiment / project. (More likely to happen)
“Plan” is a noun and a VERB !!!
Define the fundamental goal of the machine.
Who will operate it?
Is it realistic?
What is the expected lifetime?
General purpose or task specific?
Defining the Fundamental Goal of the machine
Hardly an exhaustive list
Training, Two Man Rule
Specialized training, experienced workers, properly specified and designed hardware.
IWD (or equiv.)
Remember - High Voltage is lethal.
Make use of subject matter experts regarding design and safety concerns / requirements.
High Vacuum (1X10-8 Torr or better)?
Oil less pumping system?
Consider pumping and venting time.
Viewports and diagnostic access.
Limited access / egress issues.
Use of standard vacuum ports, flanges, clamps, hoses etc.
Use proper seals to achieve the required vacuum levels.
CLEANLINESS IS ESSENTIAL FOR HIGH VACUUM !!!!
Partial pressure? Types of gasses used? High pressure? Extreme High Pressure?
Different than vacuum especially in sealing practices.
Requires review by LANS subject matter experts review and approval.
Must be redundant.
Must be engineered.
Must be approved.
Must be failsafe.
Consider the consequences of bypassing interlocks and the ability to continue operations in a bypassed mode. VERY DANGEROUS!!!!!!!!!!!!!!!!
Also must be engineered, approved, failsafe.
Recognizable by personnel.
Minimize tripping hazards and head bump hazards.
Access and Egress.
Provide proper routing of cables, power lines, vacuum lines, water lines, air lines.
Be aware that many of these utilities are not compatible in common race ways.
Hazards involved, i.e. Radiation, Laser, Hazardous Materials, Gasses etc.
Requires special handling.
Requires Safety Shoes!
Electrical (insulated feed throughs)
Water feed throughs.
Signal feed throughs (control cables, diagnostic feed troughs etc.)
Who made this?
Where are the drawings?
I need to duplicate this, can you help me?
I need to set up this experiment 6 months from now. Will I or my assistant remember how we did it?
Re entrant tubes
Alignment viewing and capabilities
Handling: forklift access, crane, hazardous material (additional training required).
Have fun !!!!
