Status report on the radio frequency accelerating system of the APS at Argonne

Abstract: Argonne National Laboratory is designing a 7-GeV Advanced Photon Source (APS). The RF systems of the APS include MHz and MHz systems for the Positron Accumulator Ring (PAR), a multicell MHz system for the booster synchrotron, and a system of mode-damped, single-cell MHz cavities for the storage ring. The authors describe the design of the PAR cavities, the configuration of the booster system, test results of the junction circulator developed for the cavities, and results of higher-order mode damping as applied to the storage ring cavities.<

Ethernet Ring

Name configured for the Ethernet ring.


Status of the Ethernet ring RAPS messages.

  • NR—Indicates that there is no request for APS on the ring.

  • SF—Indicates that there is a signal failure on the ring.

  • —Indicates that there are active forced-switch requests in the ring.

  • —Indicates that there are active manual-switch requests in the ring.

Ring Protection Link Blocked

Blocking on the ring protection link: Yes or No.

No Flush

Indicates the value of the Do Not Flush (DNF) flag in the received RAPS PDU. If the value is Yes, then FDB flush is not triggered as part of processing of the received RAPS PDU.

This parameter is the reference to the blocked ring port. If the east ring port is blocked, the Blocked Port Reference (BPR) value is 0. If the west ring port is blocked, the BPR value is 1. If both ring ports are blocked, this parameter can take any value. If both east and west ports are blocked or not blocked, the value would be 0. This field is valid only when Gv2 is supported.

Blocked Port Reference

Reference of the ring port on which traffic is blocked.


Indicates whether the node is the originator of the RAPS messages.

Remote Node ID

Identifier (in MAC address format) of the remote node.

APS Status

This app provides high-level status information and notifications for the Advanced Photon Source (APS) at Argonne National Laboratory. The information is updated at ~1 minute intervals. Swipe horizontally or use tabs to change views.
There's a selection of home-screen widgets with beam current and other high-level parameters. Color is used to indicate a problem. Clicking on the widget brings up the full app.
If the large (2x1) widget is used, it posts information to the notification bar and also optionally provides audible alerts. The alerts are configured via the menus in the main application interface.
Permissions required: network access is required in order to retrieve the information from the APS web server. There are no ads.
Note: your screen will stay on and unlocked as long as this application is in the foreground.

Advanced Photon Source

The Advanced Photon Source (APS) at Argonne National Laboratory (in Lemont, Illinois) is a national synchrotron-radiation light source research facility funded by the United States Department of EnergyOffice of Science. The facility "saw first light" on March 26, Argonne National Laboratory is managed by UChicago Argonne LLC, which is composed of the University of Chicago and Jacobs Engineering Group.

Using high-brilliance X-ray beams from the APS, members of the international synchrotron-radiation research community conduct forefront basic and applied research in the fields of materials science and biological science; physics and chemistry; environmental, geophysical and planetary science; and innovative X-ray instrumentation. As of [update], APS was the facility at which 21 of the 30 known g-protein coupled receptorprotein structures had been solved.[1]

How APS works[edit]

Electrons are produced by a hot cathode that is heated to about 1,&#;°C (2,&#;°F). The electrons are accelerated to relativistic speeds (+% of the speed of light) with an energy of &#;MeV in a linear accelerator.[2] From the linear accelerator, the electrons are injected into the booster synchrotron. Here, the electrons are sent around an oval racetrack of electromagnets, providing further acceleration. Within one-half second, the electrons reach 7&#;GeV of energy.[3] Upon reaching that energy, the electrons are injected into the storage ring, a 1,metre (3,&#;ft) circumference ring of more than 1, electromagnets.[4]

Once in the storage ring, the electrons produce x-ray beams that are available for use in experimentation. Around the ring are 40 straight sections. One of these sections is used to inject electrons into the ring, and four are dedicated to replenishing the electron energy lost though x-ray emission by using 16 radio-frequency accelerating cavities. The remaining 35 straight sections can be equipped with insertion devices.[5] Insertion devices, arrays of north-south permanent magnets usually called “undulators” or "wigglers", cause the electrons to oscillate and emit light in the invisible part of the electromagnetic spectrum. Due to the relativistic velocities of the electrons, that light is Lorentz-contracted into the x-ray band of the electromagnetic spectrum.[5]

The Experiment Hall surrounds the storage ring and is divided into 35 sectors, each of which has access to x-ray beamlines, one at an insertion device, and the other at a bending magnet.[6] Each sector also corresponds to a lab/office module offering immediate access to the beamline.[7]

Features and improvements[edit]

So called "micro-beams" (reduced cross-section, increased energy density) have been implemented in conjunction with rapid detection methods to improve the ability to obtain structure information from the small, weakly diffracting, radiation-sensitive protein crystals characteristic of membrane proteins.[1] By the s, a new storage ring technology is proposed to have been installed at APS (multibend achromat) which should provide increased beam intensity with nanometer-level beam cross-sections.[1]
