Robot vs. grout

Armed with a 4-foot lance and capable of navigating through a 16-inch-diameter sewer pipe, a tank-like robot named IGoRR recently helped remove 50 gallons of rock-hard grout from inside the Fermilab Neutrino-Muon beamline.

For six weeks this summer, a team led by AD Project Engineer Ryan Schultz remotely directed IGoRR as it blasted and chipped away at the mound of grout with a high-pressure water jet.

"It was a challenging, exhausting and rewarding experience," said Schultz, who conceived the idea for IGoRR and worked with two companies to develop it.

Last year, workers tried to fill concavities in the lower half of the beam pipe with grout to prevent any water that might leak into the pipe from collecting. Unfortunately, the grout hardened in places it wasn't supposed to. It had to be removed, and it proved to be a difficult problem to solve. The grout had 3 times the compressive strength of sidewalk concrete.

"We got the really good stuff," said AD engineering physicist Mike Geelhoed. To complicate matters, it was located 280 feet down the pipe.

After investigating several removal techniques, Schultz decided they needed a robot-controlled water pick with the strength of a jackhammer and the precision of a surgeon.

Canadian company Inuktun supplied the robot, which was mounted with two cameras, and Michigan-based NLB provided the high-pressure pump and nozzle. Schultz and the two companies worked together to develop the robot's articulating arms, designed to hold and steer the water blasting nozzle. Once they put it all together, IGoRR—Inuktun Grout Removal Robot—was born.

The team remotely operated IGoRR, directing it to aim a 20,000-psi jet of water at the grout. It was able to control the water jet with extreme precision. Only six weeks later, the hill of grout was a heap of rubble.

"That's not too shabby for something no one had ever done before and in that amount of time," Geelhoed said. "There wasn't really a textbook on how to do this. It was a great team effort."

And the team included IGoRR.

"Robots are getting more sophisticated and cheaper with time," Schultz said. As the laboratory ramps up beam intensities destined for the Intensity Frontier, radiation levels and exposure will increase. That's where robots like IGoRR can help, he said, performing tasks that limit exposure. "I believe robots have a future at Fermilab."

Computing for better accelerators

Panagiotis Spentzouris

Panagiotis Spentzouris, principal investigator of the ComPASS project and head of the Accelerator and Detector Simulation Department, wrote this column.

The path for scientific discovery at the three frontiers of high-energy physics is paved with advances in theory, experiment and simulation. In accelerator science, numerical modeling and simulation are essential for the development of new particle acceleration concepts and technologies and for the design, optimization and successful operation of accelerators.

Because of the complexity of accelerator components and the many physics processes involved in describing the behavior of particle beams as they travel through these components, high-fidelity numerical models require massive computations on powerful supercomputers. These models allow accelerator scientists to achieve higher accuracy, shorten the turnaround time in designing and optimizing accelerators, and reduce cost by lowering the number of trial-and-error cycles needed for producing accelerator component prototypes.

The Community Project for Accelerator Science and Simulation (ComPASS) is a collaboration of about 20 senior scientists – computational accelerator scientists, computer scientists and mathematicians from national laboratories, universities and private companies. Its mission is to develop simulation tools that can effectively make use of extreme-scale computing resources. Recently, ComPASS was awarded $1.8 million per year for three years under the third installment of the DOE program for Scientific Discovery through Advanced Computing (SciDAC3) through a partnership with DOE's High Energy Physics and Advanced Scientific Computing Research programs.

Under SciDAC3, ComPASS will deploy applications that will enable accelerator science advances at the Intensity and Energy Frontiers. Collaborating with other accelerator scientists, the ComPASS researchers use simulations to:

  • develop new technologies and techniques that maximize particle acceleration in the shortest possible distance,
  • investigate the potential of new techniques, technologies and materials for high-gradient acceleration,
  • optimize the design of Intensity Frontier accelerators such as Project X, and
  • explore the options for the next generation of Energy Frontier machines.

We face many challenges as we push to advance accelerator technology using cutting-edge computing technology, which are both evolving at the same time. With the support of the accelerator community and the DOE programs, the problem-solving minds of the ComPASS collaboration will meet these challenges.

Safety Update

ES&H weekly report, Sept. 11

This week's safety report, compiled by the Fermilab ES&H section, contains two incidents.

A contract employee suffered a back strain when he lifted a garbage can full of garbage and water. Medical treatment and lost time make this case a DART.

An employee experienced a minor skin rash when his wrist made contact with the dirty surface of a cable tray. He received first-aid treatment.

Auger determines pp inelastic cross-section at √s = 57 TeV

From CERN Courier, Aug. 23, 2012

Ultra-high-energy cosmic-ray particles constantly bombard the atmosphere at energies far beyond the reach of the LHC. The Pierre Auger Observatory was constructed with the aim of understanding the nature and characteristics of these particles using precise measurements of cosmic-ray-induced extensive air showers up to the highest energies. These studies allow Auger to measure basic particle interactions, recently in an energy range equivalent to a centre-of-mass energy of √s = 57 TeV.
