           <p>The collaboration operates and collects data from the Compact Muon Solenoid, one of two general-purpose particle detectors at CERN’s Large Hadron Collider. Data collected by CMS are distributed to CMS institutions in over forty countries for physics analysis.</p>
           <p>In 2018, CMS embarked on a process to select a new data management solution. The previous solution was over a decade old, difficult to maintain, and would not easily adapt to the data rates and technologies used for data transfers in the HL-LHC era. As a result of this selection process, CMS decided to adopt Rucio which was, at the time, used by on major experiment and a couple of smaller experiments.</p>
           <p>This choice has been a good one for CMS, allowing them to no longer operate a service at each of more than 50 data sites, to scale easily to new rates of data transfer, and to adopt new technologies for data transfer as needed. CMS aggregate data rates, managed by Rucio, regularly top 40 GB/s and have been proven to reach 100 GB/s.</p>

DUNE consists of two neutrino detectors situated underground with roughly 1300 km between the near and far detectors. The near detector will be located on site at Fermi National Accelerator Laboratory with the far detector located 4850 ft underground at Sanford Underground Research Facility in Lead, SD. These detectors will be exposed to the neutrinos created by the Long Baseline Neutrino Facility at Fermilab.</p>
+          <p>The raw data produced from the DUNE detectors are unique compared with other HEP experiments for both readout of neutrino interactions and observation of astrophysical events. The DUNE far detectors will consist of several large Liquid Argon Time Projection Chambers filled with approximately 17 kilotons of liquid argon. The far detector data produced from a single trigger of DAQ can vary in size from 100 MB for neutrino interaction candidates to larger than 100 TB for supernova burst candidates. The cataloging and replication of the large data volumes poses an interesting challenge for DUNE when trying to optimize workflows with large I/O requirements based upon these large volume trigger records. From the beginning, DUNE chose Rucio to manage data distribution, replication, and removal. As well, DUNE has become an active part of the Rucio development community as the experiment brings unique needs to data management.</p>
