The survey will be split over two deep fields covered by the the Subaru\/Hyper Suprime-Cam (HSC) Survey: XMM-LSS and E-COSMOS. In the context of existing and on-going cosmology campaigns with SCUBA-2, S2LXS can be considered a wide and deep tier to complement the SCUBA-2 Cosmology Legacy Survey (Geach et al. 2017), and on-going <a href=\"http:\/\/www.eaobservatory.org\/jcmt\/science\/large-programs\/s2-cosmos\/\">S2-COSMOS<\/a> and <a href=\"http:\/\/www.eaobservatory.org\/jcmt\/science\/large-programs\/studies\/\">STUDIES<\/a> Large Programmes, which survey smaller areas to higher sensitivity.<\/p>\n<p style=\"text-align: justify\">S2LXS will directly detect 370 S_850&gt;8 mJy point sources, probing the brightest and highest redshift submillimetre galaxies. Since the confusion-limited sensitivity of Herschel\/SPIRE is comparable to the S2LXS sensitivity, all S2LXS galaxies at 0 &lt; z &lt; 4 will be detected in the SPIRE bands, while z &gt; 4 sources will drop out, making S2LXS an efficient high-redshift factory for efficient follow-up with sensitive interferometers. The deep HSC imaging will deliver samples of tens of thousands of z &gt; 4 QSOs and 4 &lt; z &lt; 7 LBGs. S2LXS is designed to have a strong synergy with the HSC survey, with UVOIR-selected galaxy and QSO samples directly matched and cross-correlated with the wide-field 850\u03bcm imaging. This will reveal the cosmological evolution of dust enrichment, obscured star-formation, black hole growth and the link between environment and star formation out to the epoch of reionization.<\/p>\n<div id=\"attachment_7119\" style=\"width: 609px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey.png\"><img aria-describedby=\"caption-attachment-7119\" loading=\"lazy\" class=\"wp-image-7119\" src=\"https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey.png\" alt=\"\" width=\"599\" height=\"478\" srcset=\"https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey.png 1204w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey-300x239.png 300w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey-768x612.png 768w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey-1024x816.png 1024w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey-188x150.png 188w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_survey-150x120.png 150w\" sizes=\"(max-width: 599px) 100vw, 599px\" \/><\/a><p id=\"caption-attachment-7119\" class=\"wp-caption-text\">A comparison of survey depth and area for a range of submm\/mm surveys, indicating how S2LXS fills a niche, detecting ULIRG-class galaxies at z~2 over 10 square degrees, directly complementing S2CLS.<\/p><\/div>\n<div id=\"attachment_7121\" style=\"width: 611px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings.png\"><img aria-describedby=\"caption-attachment-7121\" loading=\"lazy\" class=\"wp-image-7121\" src=\"https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings.png\" alt=\"\" width=\"601\" height=\"306\" srcset=\"https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings.png 1280w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings-300x153.png 300w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings-768x391.png 768w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings-1024x522.png 1024w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings-250x127.png 250w, https:\/\/www.eaobservatory.org\/jcmt\/wp-content\/uploads\/sites\/2\/2017\/06\/s2lxs_pointings-150x76.png 150w\" sizes=\"(max-width: 601px) 100vw, 601px\" \/><\/a><p id=\"caption-attachment-7121\" class=\"wp-caption-text\">Field layout of S2LXS, focusing on the XMM-LSS and E-COSMOS field.
