Keith Anderson Anderson

Keith Anderson's engineering and design portfolio includes projects solving various problems encountered at Fermi National Accelerator Laboratory. Some examples include: 1) Designing a remotely controlled periscope structure to view the entire decay pipe window from 15 feet away. 2) Capturing airflow to redirect it across the NuMI horn strip line for increased cooling during higher intensity beam operations. 3) Developing a delivery system using video and lighting to insert a 50-pound inspection robot through a small access point into the BNB decay pipe.

ENGINEERING AND DESIGN PORTFOLIO Keith F. Anderson Technical Specialist Fermi National Accelerator Laboratory
Hello. I am Keith Anderson The following slide show provides a brief summary of my Engineering and Design projects. Thank you in advance for viewing.
Problem: Handed two first surface mirrors and a spotting scope and asked to mount the mirrors 15’ apart in a structure that can be manipulated by an overhead crane and lowered in the chase to view the decay pipe window.
Solution: Design a Periscope with motorized gimbal mounts for the mirrors that can be remotely manipulated so that the Periscope can remain fixed but the entire surface of the window can be viewed.
Problem: Provide more airflow across the flags of the NuMI horn strip line in order to provide sufficient cooling so that it can be used at the higher intensity beam power of the Nova project.
Solution: Capture airflow from airstream below and to the side of the horn and redirect it up an in- between the strip line where there is no airflow.

Problem: Insert a 50 pound inspection robot into the 50 meter BNB decay pipe using the only access point available. A 2 foot diameter hole through 8 feet of steel shielding that is 9 feet above ground level and 20 feet away from the nearest point a person can stand.
Solution: Design a delivery system with video and lighting that not only gets the robot into the hole but also provides a runway and retractable ramp that allows the robot to traverse the 24 inch vertical drop at the far end of the hole.

Problem: Remove the 4,000 pound BNB horn from it’s vault with a failure of it’s positioning platform that will not allow it to be lowered onto it’s transport rails.
Solution: Develop a procedure and fixtures to safely raise and support the horn off of it’s frozen adjusting jacks that will also allow for a rail system that can be used for rolling the horn into it’s transport coffin.
The following are some designs that weren’t absolutely necessary, but either improved an existing design or simplified a task.
Horn hanger spring positioners.The original design used extension springs to hold the hangers from flopping around. Even though they did this, they did not allow for precise positioning of the hangers which made connection to the module difficult. My new design still allowed the hangers to pivot but was precise enough to hold them in the primary operating position.This design was later implemented on the Nova target hangers.
This simple stand and some slight modifications to the Horn 1 inner conductor support fixture made the horn 1 inner to outer conductor assembly both simpler and safer in that it was no longer necessary to dismantle the entire fixture around the inner conductor while it was hanging from the crane. • The inner conductor could be raised vertical and placed in the stand and with the removal of a few bolts be lifted out of the top of the fixture.The original design and procedure had us dismantling the fixture from the bottom up while the whole thing was suspended from the crane.This was both hazardous to personnel and the fragile inner conductor.
Target hall trolley rail casters. I designed these casters to simplify and expedite the movement of the trolley rails from the elevator shaft to the target hall.The old process of using a rolling gantry hoist was cumbersome and time consuming.
The following are some designs that I did that weren’t used because we went a different route or just weren’t financially viable.
Nova baffle tube stretching fixture. I designed this fixture to grip the end of the baffle tube and apply a constant force to stretch the baffle tube over the graphite core.
Horn vent line support bracket. I designed this bracket to reduce mass and simplify the installation of the vent line.This was intended to replace the large stainless steel clamps that are currently used.This bracket is aluminum and would be welded to the water tank.
Camera penetration shield door. I designed this sliding shield door to cover the camera penetrations in the C-0 hot storage facility.
Thank you very much for taking your time to read through this.
