Thank you for submitting a proposal at CHESS. If you haven't made it to this step yet, please review the Prospective User Guide.

After submission, proposals are accepted by the CHESS User Office and sent to Peer (if applicable) and Safety Reviewers. Once scoring is concluded, we work internally with staff and scientists to schedule as many proposals as possible. Unfortunately, we can not accommodate all submitted proposals. Proposals that are not feasible at the selected beamline or receive poor scores will not be scheduled. You will be notified by CHESS staff if we are able to schedule your proposal. 

Whether you were awarded beam time or not, a proposal will work as the first beamtime request after that a Beam Time Request (BTR) will need to be submitted for a chance at beam time in future run cycles.  Check the deadlines page for date-specific information. The second BTR request will be labeled with the proposal number then the letter B. For example, 3287-B. The third BTR will be labeled with the proposal number then the letter C and onward. 

Following submission, the BTR will be reviewed by our safety team. Once scoring is concluded, we work internally with staff and scientists to schedule as many BTRs as possible. You will be notified by CHESS staff if we are able to schedule your proposal. You can submit as many BTRs as needed for ACTIVE proposals, please limit to one per run cycle. Proposals that have expired will not show in the dropdown as an option. 

Please reach out the CHESS User Office at CHESSUserOffice@cornell.edu with any questions or concerns.

All CHESS Users will need their own computer account to collect data and participate in an experiment. Since CHESS is part of the Cornell Laboratory for Accelerator-based ScienceS and Education (CLASSE), these computer accounts are typically referred to as “CLASSE accounts”.

If you are an owner, creator, collaborator, or principal investigator of a scheduled Beam Time Request (BTR) that has taken the CHESS User Exam, you should have received an email from CLASSE IT to set up your password and log into the account. The account will be valid through the experimental run and can be extended upon request using the CLASSE-IT Service Request Form. Your CLASSE account is how to login into BeamPASS. If you forgort your password click "Forgot password" at login. If you do not have a valid CLASSE ID, please click "Don't have an account?" at log in and complete the required form. You will receive an email to activate. 

To access data using your CLASSE ID, first please verify that you are listed as the Owner, Creator, Principal Investigator (PI), or Collaborator on a scheduled BTR by following these steps: 

1. Log into BeamPASS,
2. Click Home,
3. Click "All Proposals"
4. Click the ID number in the left-hand column
5. Scroll down to view the box titled Investigators,
6. If you need to add or remove a collaborator, please email CHESSUserOffice@cornell.edu

Then:

1. If you have not done so, take the CHESS User Exam. Please refer to Take the CHESS User Exam. 
   • Successfully completing the CHESS User Exam automatically triggers the creation of a CLASSE account.
2. Check your spam folder for an email from service-classe@classe.cornell.edu with the subject line “New CLASSE computer account created”.
   • There will be instructions to activate your account within that email.
   • If you can't find the email, click here to manually activate your CLASSE account by creating a new password.

Please note: your CLASSE account may have expired. Please contact the CLASSE IT with questions

https://www.classe.cornell.edu/duo. 

This Duo management portal walks you through the process of enrolling with CLASSE Duo and installing any necessary clients and should take about 5 minutes.  

CHESS uses NoMachine Enterprise Client as an easy-to-use connection interface to allow access to a station computer remotely. 

Please note: you will need a CLASSE Account to connect remotely. Please refer to Activate your CLASSE Account in this guide before following the steps below.

Instructions on how to install and configure the software are HERE.

• Please test the remote connection at least a week before your scheduled remote beam time.  You can test your connection without interfering with CHESS experiments on a dedicated test computer as described HERE. You will obtain access to the actual station computer controlling the experimental equipment when your remote beam time starts. Your access to the station computer will end when your beam time ends. You will be able to access your data after the beam time ends. Please refer to Data Retrieval after Experiment.

Wilson Lab is expanding! We have added an additional experimental hall onto Wilson Lab. Parking and Building access have changed. 

• Parking - Users have reserved areas to park in the Wilson Parking Lot - reserved parking is available in the last row in the parking lot (closest to Wilson Lab). "ME" Parking Permits are required for our parking lot on Synchrotron Drive between 8 am-5 pm Monday-Friday. There is additional parking available with a parking pass in the lots labeled ME here. We have a limited number of parking passes available for Users (maximum of 2 per group) which can be requested during check-in. Parking passes need to be returned at check-out. Other parking options can be found via Cornell Transportation.
• Building Access - Some doors may be inaccessible during this run. The main User Entrance will be via the loading dock, you will see signs directing you here from the reserved User Parking area. The fifth-floor entrance across from the Cornell Athletic Fields will remain open as well. Please walk down the loading dock, following all posted signage. Once inside the User Office is the first office to the right (room 147), if unavailable please proceed down the hall to CHESS Operations. 
• 

The User Office has moved to the first floor in Room 147. 

• Upon arrival, please report to the CHESS User Office area located on the first floor by walking down the loading dock at 161 Synchrotron Drive. Follow the signs down the ramp and then the directions on the doors.
  • Here we will take care of temporary parking permits and card access to the building.
  • If this is your first time at CHESS, the CHESS Operator will give you a brief tour and overview of the experimental area when you arrive. This should take about 15-20 minutes.

Wireless network access is provided by Cornell University. Please contact the CIT Service Desk with any problems. We recommend using these networks, in order of preference:

1. eduroam (preferred): if you belong to a participating institution, then you can connect to eduroam using your institutional login credentials [instructions here]. Notes:
   • Two common mistakes when trying to log into eduroam are:
     • Using one's CLASSE credentials instead of one's Cornell credentials.
     • Omitting "@cornell.edu" from the username. You must log into eduroam as your-NetID@cornell.edu because eduroam is a cross-institution service.
   • If you have a CLASSE-managed laptop, you need to follow a special procedure to connect them to eduroam -- see ConfigureEduroam. By default, they'll try to use CLASSE authentication, which cannot work with eduroam.
2. Cornell-Visitor: Per device registrations are valid for one day [instructions here].
3. RedRover: for anyone with a Cornell NetID [instructions here (but select RedRover instead of eduroam)].
   • If you do not have a Cornell NetID, you can request a Cornell GuestID through CLASSE for use with RedRover

During your experiment, you can request support from a CHESS operator and CHESS scientists through our online REmote ACcess Help (REACH) system. REACH is monitored 24 hours/day during the experimental run.

Information regarding the status of the accelerator and updates that are important for all CHESS users can be found on the CHESS status page here.

Moreover, each beamline has a beamline specific status page:

• Beamline 1A3 (SMB): http://new-status.chess.cornell.edu/ID1A3
• Beamline 2A (PIPOXS): http://new-status.chess.cornell.edu/ID2A
• Beamline 3A (FAST): http://new-status.chess.cornell.edu/ID3A
• Beamline 3B (FMB): http://new-status.chess.cornell.edu/ID3B
• Beamline 4B (QM²): http://new-status.chess.cornell.edu/ID4B
• Beamline 7A (HP BioSAXs & BioSAXS): http://new-status.chess.cornell.edu/ID7A
• Beamline 7B2 (HP Bio MX & FlexX): http://new-status.chess.cornell.edu/ID7B

Data collected at CHESS beamlines are written to a centralized data acquisition and storage system known as CHESS-DAQ. This system consists of a dedicated high-speed network that connects the experimental stations to hundreds of terabytes of enterprise-class redundant disk arrays, as well as an offsite magnetic tape library for long-term archival.

Instructions for retrieving your data from CHESS-DAQ can be found HERE. The recommended method is Globus.

Users will receive an email from the CHESS User Office to solicit feedback on the experimental run using a brief form. Your feedback is very valuable for improving the user experience at CHESS.

Please submit the form after your experiment has concluded.

To be notified in the event of weather-related closures or other emergencies, visitors to Cornell’s Ithaca campus can sign up to receive CornellALERT text notifications by texting “CornellVisitor” to 226787. You can stop receiving messages at any time by texting “STOP” to 226787. Go to Cornell Emergency Management for more information.
